“Buster,” “Scout,” “Ace,” and “Sunshine” are all great nicknames. Some nicknames are humorous, some are affectionate, and some reveal character traits. Jesus gave Simon a nickname that we could translate as “Rocky.”

In the book of John we meet Andrew, who began following Jesus after John the Baptist called him “the Lamb of God, who takes away the sin of the world” (John 1:29). Filled with excitement, Andrew later brought his brother Simon to meet Jesus as well. And when Jesus met Simon, he looked at him and gave him a new name: Cephas. This Aramaic word means “Rock,” or “Rocky,” and in Greek it translates to Petros (“Peter”).

This nickname carries a lot of weight, and Peter becomes a major figure in the New Testament. Sometimes he speaks with courage and faith, like when he says Jesus is the “Son of the living God” (Matthew 16:16). At other times, though, Peter shows that he can be remarkably weak, like when he denies even knowing Jesus (John 18:15-27).

What should we make of this towering yet flawed figure in Jesus’ inner circle and in the early church? All of Jesus’ followers are a bit like him—sometimes strong and other times weak. The good news for Peter, though, is that Jesus never abandoned him but called him to serve despite his flaws. The good news for us, too, is that Jesus will never leave us and that he equips us to serve despite our failures.
