But turning around and seeing His disciples, He rebuked Peter & said, “Get behind Me, Satan…”

The strength of Christ’ response to Peter’s proposed alternate plan demonstrates the legitimacy of the claim, “He was tempted in all things as we are, yet without sin…” Since the alternative was folly and death with no opportunity of life for the sheep the force of the rebuke resounds the truth to answer a fool as his folly deserves.
Our worthy high priest knew that life without death, was nonexistent. The grain must die for the fruit to be yielded. He alone had capacity to bear the fruit of perfection and the ability to crush the head of the one who owned the power of death. The King must come but He must come by blood of the cross and the crown of life bestowed by the Father of lights.
