Matthew 16:19-24

I will give you the keys (authority) of the kingdom of heaven; and whatever you bind [forbid, declare to be improper and unlawful] on earth will have [already] been bound in heaven, and whatever you loose [permit, declare lawful] on earth will have [already] been loosed in heaven.” [Is 22:22; Matt 18:18] Then He gave the disciples strict orders to tell no one that He was the Christ (the Messiah, the Anointed). From that time on Jesus began to show His disciples [clearly] that He must go to Jerusalem, and endure many things at the hands of the elders and the chief priests and scribes (Sanhedrin, Jewish High Court), and be killed, and be raised [from death to life] on the third day. [Mark 8:31-9:1; Luke 9:22-27] Peter took Him aside [to speak to Him privately] and began to reprimand Him, saying, “May God forbid it! This will never happen to You.” But Jesus turned and said to Peter, “Get behind Me, Satan! You are a stumbling block to Me; for you are not setting your mind on things of God, but on things of man.” Then Jesus said to His disciples, “If anyone wishes to follow Me [as My disciple], he must deny himself [set aside selfish interests], and take up his cross [expressing a willingness to endure whatever may come] and follow Me [believing in Me, conforming to My example in living and, if need be, suffering or perhaps dying because of faith in Me].
