Mt. 16:21-28; Mk. 8:31-9:1; Lk. 9:22-27
There had been a mistaken idea among the Jews that Jesus, the Christ, the Messiah was going to come and restore the earthly kingdom of Israel to them and be their king. He began discussing His passion (suffering) with the apostles and the fact that He would go to Jerusalem and be killed by the Jewish authorities and be raised the third day.
Even though He had briefly referred to this earlier in His ministry, as the sign of Jonah, the apostles still did not grasp the impact of what Jesus had said. Peter especially was outspoken and said, “Lord this will not happen to you!”
Jesus recognized that Satan was causing Peter to look for an earthly kingdom instead of the spiritual kingdom that He was to establish. He even pointed out that some of those present would see the kingdom come with power. If the kingdom has not come yet, there are some extremely old persons still living.
He then began to teach a lesson on sacrifice to the disciples and to the others present. In order to follow Jesus, one must say, “No” to self when desires are not in harmony with living for Him. He said, “For what will it profit a man if he gains the whole world, and loses his own soul? Or what will a man give in exchange for his soul?”
