1When the Pharisees and Sadducees arrived, as a test they asked Jesus to show them a sign from heaven. 2He replied to them,“You say,‘Red sky at night,what a delight! 3Red sky in the morning,cloudy and storming.’You know how to interpret the appearance of the sky, yet you can't interpret the signs of the times? 4An evil and adulterous generation craves a sign, but no sign will be given to it except the sign of Jonah.” Then he left them and went away. 5When his disciples reached the other side, they had forgotten to take any bread along. 6Jesus said to them,“Watch out! Beware of the yeast of the Pharisees and Sadducees!” 7They began to discuss this among themselves and said, “We didn't take any bread.” 8Knowing this, Jesus said,“You who have little faith, why are you discussing among yourselves the fact that you don't have any bread? 9Don't you understand yet? Don't you remember the five loaves for the 5,000 and how many baskets you collected, 10or the seven loaves for the 4,000 and how many baskets you collected? 11How can you fail to understand that I wasn't talking to you about bread? Beware of the yeast of the Pharisees and Sadducees!” 12Then they understood that he did not say to beware of the yeast used in bread, but of the teaching of the Pharisees and Sadducees. 13When Jesus had come to the region of Caesarea Philippi, he asked his disciples,“Who do people say the Son of Man is?” 14They said, “Some say John the Baptist, others Elijah, and still others Jeremiah or one of the prophets. 15He said to them,“But who do you say I am?” 16Simon Peter answered, “You are the Christ, the Son of the living God!” 17Then Jesus said to him,“How blessed are you, Simon, son of John!For flesh and blood has not revealed this to you, but my Father in heaven has. 18I tell you that you are Peter,and it is on this rockthat I will build my church, and the forces of hellwill not overpower it. 19I will give you the keys to the kingdom of heaven. Whatever you prohibit on earth will have beenprohibitedin heaven, and whatever you permit on earth will have been permittedin heaven.” 20Then he strictly ordered the disciples not to tell anyone that he was the Christ. 21From that time on, Jesus began to show his disciples that he would have to go to Jerusalem and suffer a great deal because of the elders, the high priests, and the scribes. Then he would be killed, but on the third day he would be raised. 22Peter took him aside and began to rebuke him, saying, “God be merciful to you, Lord! This must never happen to you!” 23But Jesus turned around and said to Peter,“Get behind me, Satan! You are an offenseto me, for you are not thinking God's thoughts but human thoughts!” 24Then Jesus said to his disciples,“If anyone wants to follow me, he must deny himself, pick up his cross, and follow me continually. 25For whoever wants to save his life will lose it, but whoever loses his life for my sake will find it. 26For what profit will a person have if he gains the whole world and forfeits his life? Or what can a person give in exchange for his life? 27TheSon of Man is going to come with his angels in his Father's glory, and then he will repay everyone according to what he has done. 28Truly I tell you, some people standing here will not experiencedeath before they see the Son of Man coming in his kingdom.”
