But the Lord's word endures forever." This is the word of good news which was preached to you.
The disciples had come to hope in Jesus Christ as the Messiah. When they saw the miracles that He did, when they heard His teaching, they became convinced that He was the Messiah. When Jesus said to the disciples there at Caesarea Philippi, "Who do you say that I am?" Peter said, "You're the Messiah. You're the Son of the living God". Jesus said, "Blessed art thou, Simon Barjona: flesh and blood did not reveal this, but my Father" ( Matthew 16:17 ). They had come to believe; they were convinced that Jesus was the Messiah, but the cross changed things.
