I. Cornelius, a devout man who feared God, received a vision from an angel telling him to call for Peter. Though a seeker, man's ideas of righteousness and revelations were not enough. II. Peter preached that through Jesus, believers receive forgiveness of sins. III. Peter learned lessons as a servant: do not doubt God's word; do not steal God's glory or seek man's approval, and accept refresher courses on upholding God's truth.
