In His darkest hour, Jesus was alone. Judas betrayed Him, Peter denied Him, and the other disciples deserted Him. When He appeared to them after the Resurrection, Thomas was absent and doubted the Resurrection. It was recorded for us that Jesus did not chide Peter for denying Him, nor did he chide Thomas for doubting. He also did not chide them for deserting Him. For the 11 disciples, He forgave them and entrusted them to spread the gospel. I would not comment on Judas, as there is no record of what Jesus said about Judas after the Resurrection.
How many of us are able to forgive people who did bad things to us, and trust that they would not repeat the act? As such I think this is a good example showing how Jesus is willing to forgive, and His grace, when we sin against Him.
