18. And I tell you, you are Peter [Greek, Petros–a large piece of rock], and on this rock [Greek, petra–a huge rock like Gibraltar] I will build My church, and the gates of Hades (the powers of the infernal region) shall not overpower it [or be strong to its detriment or hold out against it].
19. I will give you the keys of the kingdom of heaven; and whatever you bind (declare to be improper and unlawful) on earth must be what is already bound in heaven; and whatever you loose (declare lawful) on earth must be what is already loosed in heaven. [Isa. 22:22.]
20. Then He sternly and strictly charged and warned the disciples to tell no one that He was Jesus the Christ.
21. From that time forth Jesus began [clearly] to show His disciples that He must go to Jerusalem and suffer many things at the hands of the elders and the high priests and scribes, and be killed, and on the third day be raised from death.
22. Then Peter took Him aside to speak to Him privately and began to reprove and charge Him sharply, saying, God forbid, Lord! This must never happen to You!
23. But Jesus turned away from Peter and said to him, Get behind Me, Satan! You are in My way [an offense and a hindrance and a snare to Me]; for you are minding what partakes not of the nature and quality of God, but of men.
24. Then Jesus said to His disciples, If anyone desires to be My disciple, let him deny himself [disregard, lose sight of, and forget himself and his own interests] and take up his cross and follow Me [cleave steadfastly to Me, conform wholly to My example in living and, if need be, in dying, also].
25. For whoever is bent on saving his [temporal] life [his comfort and security here] shall lose it [eternal life]; and whoever loses his life [his comfort and security here] for My sake shall find it [life everlasting].
26. For what will it profit a man if he gains the whole world and forfeits his life [his blessed life in the kingdom of God]? Or what would a man give as an exchange for his [blessed] life [in the kingdom of God]?
27. For the Son of Man is going to come in the glory (majesty, splendor) of His Father with His angels, and then He will render account and reward every man in accordance with what he has done.
