Through the gift of faith Peter recognized that Jesus was the "anointed one" (in Hebrew and Greek the word is translated as Messiah and Christ), and the only begotten Son of God sent by the Father in heaven to redeem a fallen human race. No mortal being could have revealed this to Peter; but only God. Jesus then conferred on Peter authority to govern the church that Jesus would build, a church that no powers could overcome. Jesus played on Peter's name which is the same word for "rock" in both Aramaic and Greek.
Spiritual rock and living stones
To call someone a "rock" is one of the greatest of compliments. The ancient rabbis had a saying that when God saw Abraham, he exclaimed: "I have discovered a rock to found the world upon." Abraham put his trust in God and made God's word the foundation of his life and the bedrock of his faith. Through Abraham God established a nation for himself. Through faith Peter grasped who Jesus truly was. He was the first apostle to proclaim that Jesus was truly the Anointed One (Messiah and Christ) and the only begotten Son of God.
The New Testament describes the church, the people of God, as a spiritual house and temple of the Holy Spirit with each member joined together as living stones (see 1 Peter 2:5). Faith in Jesus Christ makes us into rocks - spiritual stones. The Lord Jesus tests each of us personally with the same question: Who do you say that I am?
"Lord Jesus, I profess and believe that you are the Christ, the Son of the living God. You are my Lord and my Savior who has set me free from sin and deception. Make my faith strong like the Apostles Peter and Paul and give me boldness to speak of you to others that they may come to know you as Lord and Savior."
