Due to the rapid and advanced development of science today, people hardly believe that the evil spirit is still around us trying to mislead us or influence our daily decisions and lives. Nonetheless, why does the Bible, which is called the book of love and truth, bother to tell us about the evil spirit? Because the evil spirit is trying to separate us from God, blind us from seeing the truth, stop us from doing what pleases God. How could evil succeed in achieving its goal? It would do anything that leads people away from God, for example by making one believe that he is the master of oneself, by directing one's attention and focus on external values. Once we are away from love and truth, then darkness, desolation, and lies will take hold of us. However, we are not hopeless even if we are in such a situation, because God will empower us with grace and rescue us as Jesus liberated the man in today's gospel. The only thing we need to do is to put our trust in him and his infinite love, confident that he will never abandon us.
