Matthew 16:23

Get thee behind me — Out of my sight. It is not improbable, Peter might step before him, to stop him. Satan — Our Lord is not recorded to have given so sharp a reproof to any other of his apostles on any occasion. He saw it was needful for the pride of Peter's heart, puffed up with the commendation lately given him. Perhaps the term Satan may not barely mean, Thou art my enemy, while thou fanciest thyself most my friend; but also, Thou art acting the very part of Satan, both by endeavouring to hinder the redemption of mankind, and by giving me the most deadly advice that can ever spring from the pit of hell. Thou savourest not — Dost not relish or desire. We may learn from hence, That whosoever says to us in such a case, Favour thyself, is acting the part of the devil: That the proper answer to such an adviser is, Get thee behind me: That otherwise he will be an offence to us, an occasion of our stumbling, if not falling: That this advice always proceeds from the not relishing the things of God, but the things of men. Yea, so far is this advice, favour thyself, from being fit for a Christian either to give or take, that if any man will come after Christ, his very first step is to deny, or renounce himself: in the room of his own will, to substitute the will of God, as his one principle of action.
