Unforgiveness would lead to torture

 The Bible says un-forgiveness would lead to torture in Matthew 18:34-35, where it describes a parable of a servant who, after being forgiven his massive debt, refused to forgive a fellow servant who owed him a small amount. In anger, his master "handed him over to the tormentors until he should pay all that was due". 

Jesus concludes this parable by stating that the heavenly Father will "do also to you if each of you, from his heart, does not forgive his brother his trespasses". 

The parable's meaning: The "torturers" represent the spiritual and emotional torment that comes from un-forgiveness. It can lead to emotional pain, bitterness, and other sins like depression and slander.

Spiritual consequence: The passage explains that being "handed over to the tormentors" is a spiritual consequence of un-forgiveness, indicating a denial of God's own forgiveness to us unless we extend it to others.

God's perspective: The passage frames un-forgiveness as a refusal to show mercy, which the master in the parable saw as a wicked act. Consequently, this act of unforgivness incurs the wrath of the heavenly Father.

Healing and liberation: The passage suggests that forgiving others is a key to spiritual freedom and liberation, allowing one to be free from the tormentors. 

In summary, the Bible uses the parable of the unmerciful servant to teach that a lack of forgiveness is a refusal to forgive others from the heart, which leads to spiritual, emotional, and psychological torment.
