What does it mean when Jesus says 'strengthen your brethren'?

When Jesus tells Peter to 'strengthen your brethren' after his restoration, He implies that Peter's fall would provide him with the humility and understanding necessary to minister to others. As Peter experiences grace amidst failure, he learns the importance of sharing that same grace with others who falter. The command underscores the need for mutual support and encouragement among believers, emphasizing that our weaknesses can become a source of strength for others when we point them to Christ, our Savior.
