Discouragement can be a common struggle, and there are multiple spiritual factors which can contribute to it. In John 21, Peter was wrestling with his own sense of failing Jesus, especially after he had boldly declared that he would never turn aside or deny Jesus. So the Lord meets him and the others in a familiar setting in Galilee. Peter's response to Jesus being there, and the Lord's words to him, give us great insight into how to move beyond discouragement.
