Ideas about the Kingdom of the Heavens around us and the unity of believers in Christ within it
I’ve heard it preached that, when I hold a grudge, I hurt only myself. The other person is not affected. But this is simply false. As long as either of us is holding a grudge, we are both imprisoned in it, until the one holding the grudge releases it. I must offer unlimited forgiveness, and not give in to bearing a grudge toward those who have hurt me. And I must be aware that my grudge always affects other people.
Jesus uses unforgiveness as the prime example of a stumbling block we can place in the way of a fellow believer, bringing judgment. Therefore he warns us that we must be careful to freely forgive those who come to us expressing repentance for harm they have done to us by missing the mark of either our own, or God’s, expectations for their behavior.
The New Testament uses a number of different words to describe sin, its causes and its effects, in the context of confession, repentance and forgiveness. These words are not synonyms, and distinguishing them is important to understanding many of the contexts in which they are used.
