Peter makes a stunningly clear and bold confession.
You are the Son of God, having the same character and nature and power as God the Father.
You are the Christ, the Messiah, the anointed one of God who will save His people from their sins.
Jesus is exceedingly pleased and praises Peter while at the same time making it clear that anytime a person declares the truth about Jesus they have been enabled to do so by God through His Holy Spirit.
Have we made this profession? Can you say this out loud in sincere faith with all your heart? Then know this, that is the hand of the living God in your life. God has touched your heart and opened the blind eyes of a sinner.
