John 20:19-31

19 It was the first day of the week, and that very evening, while the disciples were together with the doors locked for fear of the Jews, Jesus came and stood among them. “Peace be with you!” He said to them. 20 After He had said this, He showed them His hands and His side.
The disciples rejoiced when they saw the Lord. 21 Again Jesus said to them, “Peace be with you. As the Father has sent Me, so also I am sending you.” 22 When He had said this, He breathed on them and said, “Receive the Holy Spirit. 23 If you forgive anyone his sins, they are forgiven; if you withhold forgiveness from anyone, it is withheld.” 24 Now Thomas called Didymus, one of the Twelve, was not with the disciples when Jesus came. 25 So the other disciples told him, “We have seen the Lord!”
But he replied, “Unless I see the nail marks in His hands, and put my finger where the nails have been, and put my hand into His side, I will never believe.” 26 Eight days later, His disciples were once again inside with the doors locked, and Thomas was with them. Jesus came and stood among them and said, “Peace be with you.” 27 Then Jesus said to Thomas, “Put your finger here and look at My hands. Reach out your hand and put it into My side. Stop doubting and believe.” 28 Thomas replied, “My Lord and my God!” 29 Jesus said to him, “Because you have seen Me, you have believed; blessed are those who have not seen and yet have believed.” 30 Jesus performed many other signs in the presence of His disciples, which are not written in this book. 31 But these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in His name.

John 21:1-14

1 Later, by the Sea of Tiberias, Jesus again revealed Himself to the disciples. He made Himself known in this way: 2 Simon Peter, Thomas called Didymus, Nathanael from Cana in Galilee, the sons of Zebedee, and two other disciples were together. 3 Simon Peter told them, “I am going fishing.”
“We will go with you,” they said. So they went out and got into the boat, but caught nothing that night. 4 Early in the morning, Jesus stood on the shore, but the disciples did not recognize that it was Jesus. 5 So He called out to them, “Children, do you have any fish?”
“No,” they answered. 6 He told them, “Cast the net on the right side of the boat, and you will find some.” So they cast it there, and they were unable to haul it in because of the great number of fish. 7 Then the disciple whom Jesus loved said to Peter, “It is the Lord!” As soon as Simon Peter heard that it was the Lord, he put on his outer garment (for he had removed it) and jumped into the sea. 8 The other disciples came ashore in the boat. They dragged in the net full of fish, for they were not far from land, only about a hundred yards. 9 When they landed, they saw a charcoal fire there with fish on it, and some bread. 10 Jesus told them, “Bring some of the fish you have just caught.” 11 So Simon Peter went aboard and dragged the net ashore. It was full of large fish, 153, but even with so many, the net was not torn. 12 “Come, have breakfast,” Jesus said to them. None of the disciples dared to ask Him, “Who are You?” They knew it was the Lord. 13 Jesus came and took the bread and gave it to them, and He did the same with the fish. 14 This was now the third time that Jesus appeared to the disciples after He was raised from the dead.

John 21:15-19

15 When they had finished eating, Jesus asked Simon Peter, “Simon son of John, do you love Me more than these?”
“Yes, Lord,” he answered, “You know I love You.”
Jesus replied, “Feed My lambs.” 16 Jesus asked a second time, “Simon son of John, do you love Me?”
“Yes, Lord,” he answered, “You know I love You.”
Jesus told him, “Shepherd My sheep.” 17 Jesus asked a third time, “Simon son of John, do you love Me?”
Peter was deeply hurt that Jesus had asked him a third time, “Do you love Me?”
“Lord, You know all things,” he replied. “You know I love You.”
Jesus said to him, “Feed My sheep. 18 Truly, truly, I tell you, when you were young, you dressed yourself and walked where you wanted; but when you are old, you will stretch out your hands, and someone else will dress you and lead you where you do not want to go.” 19 Jesus said this to indicate the kind of death by which Peter would glorify God.
And after He had said this, He told him, “Follow Me.”
