Matthew 16:16-27 (NKJV)
Simon Peter answered and said, “You are the Christ, the Son of the living God.”
17 Jesus answered and said to him, “Blessed are you, Simon Bar-Jonah, for flesh and blood has not revealed this to you, but My Father who is in heaven. 18 And I also say to you that you are Peter, and on this rock I will build My church, and the gates of Hades shall not prevail against it. 19 And I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.”
20 Then He commanded His disciples that they should tell no one that He was Jesus the Christ.
21 From that time Jesus began to show to 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 the third day.
22 Then Peter took Him aside and began to rebuke Him, saying, “Far be it from You, Lord; this shall not happen to You!”
23 But He turned and said to Peter, “Get behind Me, Satan! You are an offense to Me, for you are not mindful of the things of God, but the things of men.”
24 Then Jesus said to His disciples, “If anyone desires to come after Me, let him deny himself, and take up his cross, and follow Me. 25 For whoever desires to save his life will lose it, but whoever loses his life for My sake will find it. 26 For what profit is it to a man if he gains the whole world, and loses his own soul? Or what will a man give in exchange for his soul? 27 For the Son of Man will come in the glory of His Father with His angels, and then He will reward each according to his works.
