From that time Jesus began to show to His disciples that He must go to Jerusalem, and suffer many things from the elders and chief priests and scribes, and be killed, and be raised the third day. Then Peter took Him aside and began to rebuke Him, saying, “Far be it from You, Lord; this shall not happen to You!” But He turned and said to Peter, “Get behind Me, Satan! You are an offense to Me, for you are not mindful of the things of God, but the things of men.” (Matthew 16:21-23)
It is easy to let our expectations of what God should do run ahead of the Lord – even when the Lord clearly tells us His will. Peter had recently confessed Jesus to be “the Christ, the Son of the living God” (Matt. 16:16). But, when Jesus began speaking of his torture and death, Peter objected. Do you ever argue with God and oppose what He teaches in His word? If so, then you are minding “the things of men”. Like Peter, you become a stumbling block (like Peter was on that occasion). It is instructive that previously confessing Christ did not prevent Peter from sinning against the Lord. If you have confessed Jesus is the Son of God then willingly yield to His teachings and mind “the things of God” every day.
