1. Onesimus was Paul's fellow worker who was once a slave but was now seen as a beloved brother through their new identity in Christ.
2. Paul once persecuted the church but through God's grace he became an apostle, working harder than all to spread the gospel according to his new purpose.
3. Peter, who denied knowing Jesus three times, was specifically mentioned to be told of Jesus' resurrection. Despite his failures, Jesus never gave up on Peter and his role as a leader in the early church, showing that one's true identity is found in Christ rather than past failures.
