In Matt. 18:21 Jesus talked about forgiveness and that we must forgive our brother 70 X 7 times. It is followed by the parable of the unforgiving servant. If we as Christians don’t forgive we will be delivered to the torturers. This means that God will move His hand of protection from us if we don’t forgive.
The conclusion: We as Christians who are not living for the Lord, but living in unforgiveness, can be influenced by demons. We can be harassed and even oppressed by the powers of darkness, but not possessed.
Remember: The past is in your head, the future is in your hands. (Your choice}
