Do you remember when Jesus said to the disciples that he had to go up to Jerusalem and suffer and be killed, and Peter said, “God forbid, Lord”? Jesus responded to Peter, “Get behind me, Satan! You are a hindrance to me” (Matthew 16:23). Satan’s aim in the wilderness was to hinder Jesus from suffering. Because the suffering and death of Jesus meant the final destruction of Satan and the salvation of you and me. And Satan’s aim in this church today is to hinder you from following Jesus when he says, “If anyone would come after me, let him deny himself and take up his cross daily and follow me (in the path of suffering)” (Luke 9:23).
