Jesus displays his great sacrificial love through the restoration of those who deny Him. This includes believers who have distanced themselves from their Saviour, as well as those who haven't yet put their trust in Jesus.

Matthew 26:69–75

Peter Denies Jesus

69 Now Peter was sitting outside in the courtyard. And a servant girl came up to him and said, “You also were with Jesus the Galilean.” 70 But he denied it before them all, saying, “I do not know what you mean.” 71 And when he went out to the entrance, another servant girl saw him, and she said to the bystanders, “This man was with Jesus of Nazareth.” 72 And again he denied it with an oath: “I do not know the man.” 73 After a little while the bystanders came up and said to Peter, “Certainly you too are one of them, for your accent betrays you.” 74 Then he began to invoke a curse on himself and to swear, “I do not know the man.” And immediately the rooster crowed. 75 And Peter remembered the saying of Jesus, “Before the rooster crows, you will deny me three times.” And he went out and wept bitterly.

John 21:4–25

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 yards¹ 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 brothers² 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.
