Unforgiveness

In 2 Cor.2 the Apostle Paul says that we forgive, so that satan won't be able to take advantage of us, as we aren't ignorant of his schemes. So it's clear that we have a very real enemy in the unseen realm, and that this enemy's mission is to steal, kill, and destroy. But how does the apostle suggest that we are supposed to battle this enemy? By walking in forgiveness. Forgiveness, more than anything, opens the doors for demonic torturers to buffet your life. If left un-checked, unforgiveness also has a devastating effect on our eternity.
