“He was openly talking about this. So Peter took Him aside and began to rebuke Him.
But turning around and looking at His disciples, He rebuked Peter and said, “’Get behind Me, Satan, because you’re not thinking about God’s concerns, but man’s!’”
We must see the irony here. Jesus’ close disciple, who still cannot fully understand what lies ahead or what Jesus ultimate purpose is, takes Jesus (God) aside to ‘straighten Him out’. Obviously, based on this one statement of Jesus, Peter is confused about what the future holds. The irony is that Jesus refers to one of His closest apostles as His #1 enemy. He refers to Peter as satan. Go figure!
Peter’s challenge sounds like something the enemy said during Jesus’ desert temptation, so Jesus calls Peter out. Jesus won’t play games or mince words even with those who are critical players in His future plans. The end never justifies the means with Jesus. When those who are with Him talk like the one who is ultimately against Him, He addresses it directly. It was satan who said that there would be no reason for Jesus to suffer in order to reign. It was satan who laid out before Jesus a plan for wordly success and control that did not involve suffering and submission to God. Jesus clearly identifies this with the strong, public rebuke of Peter. Peter’s rebuke becomes Jesus’ teaching point.
To be aligned with the enemy is to be against Lord Jesus.
