Mar 16:7 But go, tell his disciples AND PETER that he is going before you to Galilee. There you will see him, just as he told you.
Three women bought spices to anoint Jesus’ body only to find the tomb empty for He had risen. The angel who proclaimed the resurrection bid them to go and tell the disciples, and Peter is mentioned by name.
Peter is particularly mentioned, not as distinct from the apostles but because he had denied Christ. Perhaps the women and the rest no longer considered him part of the fold. He was a wounded warrior left by the road side to die because of what he did. So mentioning Peter by name was for his comfort and assurance to the rest that he was not past repair, if Jesus could welcome him back, who were the rest to push him away.
From experience, many brothers in Christ tend to be too quick to inflict more pain to wounded soldiers. Sometimes even leave them by the road side because they sinned (failed). We always need to remind ourselves that the nature is in each of us to deny Christ and are no better than others. It’s interesting that the Bible does not hide the scars of the heroes of the faith yet in Heb 11, their failures is not brought up but their faith. Despite our sins, failures, denial of Him, He has called us by name to restore us because He is risen.
