Matthew 17:14–20
Jesus Heals a Boy with a Demon
14 And when they came to the crowd, a man came up to him and, kneeling before him, 15 said, “Lord, have mercy on my son, for he has seizures and he suffers terribly. For often he falls into the fire, and often into the water. 16 And I brought him to your disciples, and they could not heal him.” 17 And Jesus answered, “O faithless and twisted generation, how long am I to be with you? How long am I to bear with you? Bring him here to me.” 18 And Jesus rebuked the demon, and it came out of him, and the boy was healed instantly. 19 Then the disciples came to Jesus privately and said, “Why could we not cast it out?” 20 He said to them, “Because of your little faith. For truly, I say to you, if you have faith like a grain of mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move, and nothing will be impossible for you.”

The Lord’s Faithless Bride
16:1 Again the word of the LORD came to me: 2 “Son of man, make known to Jerusalem her abominations, 3 and say, Thus says the Lord GOD to Jerusalem: Your origin and your birth are of the land of the Canaanites; your father was an Amorite and your mother a Hittite. 4 And as for your birth, on the day you were born your cord was not cut, nor were you washed with water to cleanse you, nor rubbed with salt, nor wrapped in swaddling cloths. 5 No eye pitied you, to do any of these things to you out of compassion for you, but you were cast out on the open field, for you were abhorred, on the day that you were born.
6 “And when I passed by you and saw you wallowing in your blood, I said to you in your blood, ‘Live!’ I said to you in your blood, ‘Live!’ 7 I made you flourish like a plant of the field. And you grew up and became tall and arrived at full adornment. Your breasts were formed, and your hair had grown; yet you were naked and bare.
8 “When I passed by you again and saw you, behold, you were at the age for love, and I spread the corner of my garment over you and covered your nakedness; I made my vow to you and entered into a covenant with you, declares the Lord GOD, and you became mine. 9 Then I bathed you with water and washed off your blood from you and anointed you with oil. 10 I clothed you also with embroidered cloth and shod you with fine leather. I wrapped you in fine linen and covered you with silk. 11 And I adorned you with ornaments and put bracelets on your wrists and a chain on your neck. 12 And I put a ring on your nose and earrings in your ears and a beautiful crown on your head. 13 Thus you were adorned with gold and silver, and your clothing was of fine linen and silk and embroidered cloth. You ate fine flour and honey and oil. You grew exceedingly beautiful and advanced to royalty. 14 And your renown went forth among the nations because of your beauty, for it was perfect through the splendor that I had bestowed on you, declares the Lord GOD.
15 “But you trusted in your beauty and played the whore because of your renown and lavished your whorings on any passerby; your beauty became his. 16 You took some of your garments and made for yourself colorful shrines, and on them played the whore. The like has never been, nor ever shall be. 17 You also took your beautiful jewels of my gold and of my silver, which I had given you, and made for yourself images of men, and with them played the whore. 18 And you took your embroidered garments to cover them, and set my oil and my incense before them. 19 Also my bread that I gave you—I fed you with fine flour and oil and honey—you set before them for a pleasing aroma; and so it was, declares the Lord GOD. 20 And you took your sons and your daughters, whom you had borne to me, and these you sacrificed to them to be devoured. Were your whorings so small a matter 21 that you slaughtered my children and delivered them up as an offering by fire to them? 22 And in all your abominations and your whorings you did not remember the days of your youth, when you were naked and bare, wallowing in your blood.
23 “And after all your wickedness (woe, woe to you! declares the Lord GOD), 24 you built yourself a vaulted chamber and made yourself a lofty place in every square. 25 At the head of every street you built your lofty place and made your beauty an abomination, offering yourself to any passerby and multiplying your whoring. 26 You also played the whore with the Egyptians, your lustful neighbors, multiplying your whoring, to provoke me to anger. 27 Behold, therefore, I stretched out my hand against you and diminished your allotted portion and delivered you to the greed of your enemies, the daughters of the Philistines, who were ashamed of your lewd behavior. 28 You played the whore also with the Assyrians, because you were not satisfied; yes, you played the whore with them, and still you were not satisfied. 29 You multiplied your whoring also with the trading land of Chaldea, and even with this you were not satisfied.
30 “How sick is your heart, declares the Lord GOD, because you did all these things, the deeds of a brazen prostitute, 31 building your vaulted chamber at the head of every street, and making your lofty place in every square. Yet you were not like a prostitute, because you scorned payment. 32 Adulterous wife, who receives strangers instead of her husband! 33 Men give gifts to all prostitutes, but you gave your gifts to all your lovers, bribing them to come to you from every side with your whorings. 34 So you were different from other women in your whorings. No one solicited you to play the whore, and you gave payment, while no payment was given to you; therefore you were different.
35 “Therefore, O prostitute, hear the word of the LORD: 36 Thus says the Lord GOD, Because your lust was poured out and your nakedness uncovered in your whorings with your lovers, and with all your abominable idols, and because of the blood of your children that you gave to them, 37 therefore, behold, I will gather all your lovers with whom you took pleasure, all those you loved and all those you hated. I will gather them against you from every side and will uncover your nakedness to them, that they may see all your nakedness. 38 And I will judge you as women who commit adultery and shed blood are judged, and bring upon you the blood of wrath and jealousy. 39 And I will give you into their hands, and they shall throw down your vaulted chamber and break down your lofty places. They shall strip you of your clothes and take your beautiful jewels and leave you naked and bare. 40 They shall bring up a crowd against you, and they shall stone you and cut you to pieces with their swords. 41 And they shall burn your houses and execute judgments upon you in the sight of many women. I will make you stop playing the whore, and you shall also give payment no more. 42 So will I satisfy my wrath on you, and my jealousy shall depart from you. I will be calm and will no more be angry. 43 Because you have not remembered the days of your youth, but have enraged me with all these things, therefore, behold, I have returned your deeds upon your head, declares the Lord GOD. Have you not committed lewdness in addition to all your abominations?
44 “Behold, everyone who uses proverbs will use this proverb about you: ‘Like mother, like daughter.’ 45 You are the daughter of your mother, who loathed her husband and her children; and you are the sister of your sisters, who loathed their husbands and their children. Your mother was a Hittite and your father an Amorite. 46 And your elder sister is Samaria, who lived with her daughters to the north of you; and your younger sister, who lived to the south of you, is Sodom with her daughters. 47 Not only did you walk in their ways and do according to their abominations; within a very little time you were more corrupt than they in all your ways. 48 As I live, declares the Lord GOD, your sister Sodom and her daughters have not done as you and your daughters have done. 49 Behold, this was the guilt of your sister Sodom: she and her daughters had pride, excess of food, and prosperous ease, but did not aid the poor and needy. 50 They were haughty and did an abomination before me. So I removed them, when I saw it. 51 Samaria has not committed half your sins. You have committed more abominations than they, and have made your sisters appear righteous by all the abominations that you have committed. 52 Bear your disgrace, you also, for you have intervened on behalf of your sisters. Because of your sins in which you acted more abominably than they, they are more in the right than you. So be ashamed, you also, and bear your disgrace, for you have made your sisters appear righteous.
53 “I will restore their fortunes, both the fortunes of Sodom and her daughters, and the fortunes of Samaria and her daughters, and I will restore your own fortunes in their midst, 54 that you may bear your disgrace and be ashamed of all that you have done, becoming a consolation to them. 55 As for your sisters, Sodom and her daughters shall return to their former state, and Samaria and her daughters shall return to their former state, and you and your daughters shall return to your former state. 56 Was not your sister Sodom a byword in your mouth in the day of your pride, 57 before your wickedness was uncovered? Now you have become an object of reproach for the daughters of Syria and all those around her, and for the daughters of the Philistines, those all around who despise you. 58 You bear the penalty of your lewdness and your abominations, declares the LORD.
The Lord’s Everlasting Covenant
59 “For thus says the Lord GOD: I will deal with you as you have done, you who have despised the oath in breaking the covenant, 60 yet I will remember my covenant with you in the days of your youth, and I will establish for you an everlasting covenant. 61 Then you will remember your ways and be ashamed when you take your sisters, both your elder and your younger, and I give them to you as daughters, but not on account of the covenant with you. 62 I will establish my covenant with you, and you shall know that I am the LORD, 63 that you may remember and be confounded, and never open your mouth again because of your shame, when I atone for you for all that you have done, declares the Lord GOD.”

The Resurrection
28:1 Now after the Sabbath, toward the dawn of the first day of the week, Mary Magdalene and the other Mary went to see the tomb. 2 And behold, there was a great earthquake, for an angel of the Lord descended from heaven and came and rolled back the stone and sat on it. 3 His appearance was like lightning, and his clothing white as snow. 4 And for fear of him the guards trembled and became like dead men. 5 But the angel said to the women, “Do not be afraid, for I know that you seek Jesus who was crucified. 6 He is not here, for he has risen, as he said. Come, see the place where he lay. 7 Then go quickly and tell his disciples that he has risen from the dead, and behold, he is going before you to Galilee; there you will see him. See, I have told you.” 8 So they departed quickly from the tomb with fear and great joy, and ran to tell his disciples. 9 And behold, Jesus met them and said, “Greetings!” And they came up and took hold of his feet and worshiped him. 10 Then Jesus said to them, “Do not be afraid; go and tell my brothers to go to Galilee, and there they will see me.”
The Report of the Guard
11 While they were going, behold, some of the guard went into the city and told the chief priests all that had taken place. 12 And when they had assembled with the elders and taken counsel, they gave a sufficient sum of money to the soldiers 13 and said, “Tell people, ‘His disciples came by night and stole him away while we were asleep.’ 14 And if this comes to the governor’s ears, we will satisfy him and keep you out of trouble.” 15 So they took the money and did as they were directed. And this story has been spread among the Jews to this day.
The Great Commission
16 Now the eleven disciples went to Galilee, to the mountain to which Jesus had directed them. 17 And when they saw him they worshiped him, but some doubted. 18 And Jesus came and said to them, “All authority in heaven and on earth has been given to me. 19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”

Jesus Appears to Seven Disciples
21:1 After this Jesus revealed himself again to the disciples by the Sea of Tiberias, and he revealed himself in this way. 2 Simon Peter, Thomas (called the Twin), Nathanael of Cana in Galilee, the sons of Zebedee, and two others of his disciples were together. 3 Simon Peter said to them, “I am going fishing.” They said to him, “We will go with you.” They went out and got into the boat, but that night they caught nothing.
4 Just as day was breaking, Jesus stood on the shore; yet the disciples did not know that it was Jesus. 5 Jesus said to them, “Children, do you have any fish?” They answered him, “No.” 6 He said to them, “Cast the net on the right side of the boat, and you will find some.” So they cast it, and now they were not able to haul it in, because of the quantity of fish. 7 That disciple whom Jesus loved therefore said to Peter, “It is the Lord!” When Simon Peter heard that it was the Lord, he put on his outer garment, for he was stripped for work, and threw himself into the sea. 8 The other disciples came in the boat, dragging the net full of fish, for they were not far from the land, but about a hundred yards off.
9 When they got out on land, they saw a charcoal fire in place, with fish laid out on it, and bread. 10 Jesus said to them, “Bring some of the fish that you have just caught.” 11 So Simon Peter went aboard and hauled the net ashore, full of large fish, 153 of them. And although there were so many, the net was not torn. 12 Jesus said to them, “Come and have breakfast.” Now none of the disciples dared ask him, “Who are you?” They knew it was the Lord. 13 Jesus came and took the bread and gave it to them, and so with the fish. 14 This was now the third time that Jesus was revealed to the disciples after he was raised from the dead.
Jesus and Peter
15 When they had finished breakfast, Jesus said to Simon Peter, “Simon, son of John, do you love me more than these?” He said to him, “Yes, Lord; you know that I love you.” He said to him, “Feed my lambs.” 16 He said to him a second time, “Simon, son of John, do you love me?” He said to him, “Yes, Lord; you know that I love you.” He said to him, “Tend my sheep.” 17 He said to him the third time, “Simon, son of John, do you love me?” Peter was grieved because he said to him the third time, “Do you love me?” and he said to him, “Lord, you know everything; you know that I love you.” Jesus said to him, “Feed my sheep. 18 Truly, truly, I say to you, when you were young, you used to dress yourself and walk wherever you wanted, but when you are old, you will stretch out your hands, and another will dress you and carry you where you do not want to go.” 19 (This he said to show by what kind of death he was to glorify God.) And after saying this he said to him, “Follow me.”
Jesus and the Beloved Apostle
20 Peter turned and saw the disciple whom Jesus loved following them, the one who also had leaned back against him during the supper and had said, “Lord, who is it that is going to betray you?” 21 When Peter saw him, he said to Jesus, “Lord, what about this man?” 22 Jesus said to him, “If it is my will that he remain until I come, what is that to you? You follow me!” 23 So the saying spread abroad among the brothers that this disciple was not to die; yet Jesus did not say to him that he was not to die, but, “If it is my will that he remain until I come, what is that to you?”
24 This is the disciple who is bearing witness about these things, and who has written these things, and we know that his testimony is true.
25 Now there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written.

Outline
The disciples' failure to cast out the demon reveals that Christian power comes not from self-sufficient ability but from faith that is grounded in prayerful dependence on God.
IThe Impotence of the Disciples8:31Matt.17.14-Matt.17.18
- •A father brings his demon-possessed son to Jesus after the disciples failed9:09Matt.17.14-Matt.17.15
- •The disciples, though previously commissioned and empowered, could not heal him10:32Matt.17.16
- •Jesus rebukes the faithless and twisted generation, not merely the man but the whole crowd13:16Matt.17.17
- •Jesus demonstrates his own power by instantly casting out the demon and healing the boy23:21Matt.17.18
- •Mark's account highlights the father's cry, 'I believe; help my unbelief!'23:50Mark.9.24
IIThe Potency of Prayer and Faith26:58Matt.17.19-Matt.17.20
- •The disciples ask Jesus privately why they could not cast out the demon27:41Matt.17.19
- •Jesus diagnoses their failure as little faith—trying to act in self-sufficiency rather than reliance on God27:59Matt.17.20
- •The connection between faith and prayer, and the illustration of Mitsuhiru praying before driving29:25Mark.9.29
- •Faith must be grounded in Christ, not in itself, and must cry out 'help my unbelief'32:41John.15.5
- ➜Believers must feed and grow their faith through the ordinary means of grace37:36John.17.17
The preacher prays, acknowledging that believers share the disciples' weakness and need faith that is grounded in Christ rather than self. He thanks God that prayer's power is found in its object—the Lord Jesus Christ—and asks that the church would grow through the Word and ordinary means of grace to live dependently for God's glory.
Call to response: Grow your faith through the ordinary means of grace—God's Word read, sung, preached, prayed, and visible in the sacraments—so that your confidence rests in God alone.
