John 20:20-21

20:20 When he had said this, he showed them his hands and his side. Then the disciples rejoiced when they saw the Lord. 20:21 So Jesus said to them again, “Peace be with you. Just as the Father has sent me, I also send you.”

sn When the disciples recognized Jesus (now referred to as the Lord, cf. Mary’s words in v. 18) they were suddenly overcome with joy. This was a fulfillment of Jesus’ words to the disciples in the Farewell Discourse (16:20-22) that they would have sorrow while the world rejoiced, but that their sorrow would be turned to lasting joy when they saw him again.
