Simon, Simon, behold, Satan has demanded permission to sift you like wheat; but I have prayed for you, that your faith may not fail
What right did Satan have to sift Simon (Peter) like wheat? The context reveals that Peter and the other disciples were arguing about who was going to be the greatest in the kingdom of God. In other words, they were exercising pride. Sinful pride affords Satan a huge opportunity. Peter protested that he was willing to die or go to prison for the sake of Christ. But Jesus told him that, before the day was over, Peter would deny Him three times, and he did.It is critical that Christians understand their vulnerability to demonic influence. Those who say a demon cannot influence a believer's life have left us with only two possible culprits for the problems we face: ourselves or God. If we blame ourselves, we feel hopeless because we can't do anything to stop what we're doing. If we blame God, our confidence in Him as our benevolent Father is shattered. Either way, we have no chance to gain the victory which the Bible promises us. In reality we are in a winnable war against the defeated kingdom of darkness. But the lies of Satan can gain a measure of control if we believe them.
