Peter testified by his experience that the prophecies about the Messiah written throughout Scripture were fulfilled in Jesus, proving the legitimacy of the Gospel. Peter bore witness in this passage that he, James and John literally saw the majesty of Christ firsthand, and heard the Father affirm the identity of His Son (Matthew 17:1-8; Mark 9:2-8; Luke 9:28-36). Jesus was the promised Messiah who had come to earth.

Jesus is Lord. None of these facts are cleverly contrived myths. As God the Father instructed the disciples to listen to Jesus’ teaching, in the same way, we should listen to the Scriptures. These are God’s divine revelation to His people, and they carry the same authority as Jesus’ words when He was on earth. The Scriptures are the very words of God.

Why is the eyewitness testimony of the apostles useful for fighting doubts we might have about the truth of the Gospel?
