Luke 9:18-27
And it happened that while He was praying alone, the disciples were with Him, and He questioned them, saying, “Who do the people say that I am?” They answered and said, “John the Baptist, and others say Elijah; but others, that one of the prophets of old has risen again.” And He said to them, “But who do you say that I am?” And Peter answered and said, “The Christ of God.” But He warned them and instructed them not to tell this to anyone, saying, “The Son of Man must suffer many things and be rejected by the elders and chief priests and scribes, and be killed and be raised up on the third day.”
And He was saying to them all, “If anyone wishes to come after Me, he must deny himself, and take up his cross daily and follow Me. For whoever wishes to save his life will lose it, but whoever loses his life for My sake, he is the one who will save it. For what is a man profited if he gains the whole world, and loses or forfeits himself? For whoever is ashamed of Me and My words, the Son of Man will be ashamed of him when He comes in His glory, and the glory of the Father and of the holy angels. But I say to you truthfully, there are some of those standing here who will not taste death until they see the kingdom of God.”
Matthew 16:13-28
Now when Jesus came into the district of Caesarea Philippi, He was asking His disciples, “Who do people say that the Son of Man is?” And they said, “Some say John the Baptist; and others, Elijah; but still others, Jeremiah, or one of the prophets.” He said to them, “But who do you say that I am?” Simon Peter answered, “You are the Christ, the Son of the living God.” And Jesus said to him, “Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven. I also say to you that you are Peter, and upon this rock I will build My church; and the gates of Hades will not overpower it. I will give you the keys of the kingdom of heaven; and whatever you bind on earth shall have been bound in heaven, and whatever you loose on earth shall have been loosed in heaven.” Then He warned the disciples that they should tell no one that He was the Christ.
From that time Jesus began to show His disciples that He must go to Jerusalem, and suffer many things from the elders and chief priests and scribes, and be killed, and be raised up on the third day. Peter took Him aside and began to rebuke Him, saying, “God forbid it, Lord! This shall never happen to You.” But He turned and said to Peter, “Get behind Me, Satan! You are a stumbling block to Me; for you are not setting your mind on God’s interests, but man’s.”
Then Jesus said to His disciples, “If anyone wishes to come after Me, he must deny himself, and take up his cross and follow Me. For whoever wishes to save his life will lose it; but whoever loses his life for My sake will find it. For what will it profit a man if he gains the whole world and forfeits his soul? Or what will a man give in exchange for his soul? For the Son of Man is going to come in the glory of His Father with His angels, and will then repay every man according to his deeds.
“Truly I say to you, there are some of those who are standing here who will not taste death until they see the Son of Man coming in His kingdom.”
