We cannot stop Satan and evil spirits from attacking our minds, but we don’t have to allow their thoughts to become our thoughts. That is, we don’t have to dwell upon demonic ideas and suggestions, taking possession of them. As it has been said, “You can’t keep the birds from flying over your head, but you can keep them from making a nest in your hair.”
Additionally, we should be careful not to subject our minds to ungodly influences whenever it is within our control. When we sit down in front of the television for an hour, or read the newspaper, we are putting out the welcome mat to be influenced with thoughts that may be satanic. Directly after He told the parable of the sower and the soils, Jesus warned, “Take care what you listen to” (Mark 4:24). Jesus knew the destructive effects of listening to lies, allowing Satan to plant his “seeds” in our hearts and minds. Those seeds may grow up into “thorns and thistles” which will ultimately choke the Word of God from our lives (see Mark 4:7, 18-19).
