* An un-forgiving hearts builds up strongholds, mind garrisons that must be pulled down because they are against God’s will: ‘A brother offended is harder to win than a strong city, and contentions are like the bars of a castle’ Prov.18:19. The bars of a castle constitute a stronghold; they keep out unwelcome assailants, but also keep good from coming in. A stronghold in the heart quickly becomes an enemy within; what the heart believes, the mouth speaks, and the decisions made and actions taken are so influenced.
* The one that harbours un-forgiveness may likely make negative confessions about the offender and himself. Since Jesus gave us understanding that we have what we say Mk.11:23, an evil speaking person is prevented from the personal transformation necessary to receive the blessing stored up , the good, acceptable and perfect will of God Rom.12:2. Rather than be guided by the Holy Spirit, his decisions and actions are influenced by wrong thinking Prov.23:7.
* If a person hurts others because he is under the influence of an evil spirit, forgiving him makes it imperative for his tormentor to leave when commanded to do so. The condemnation of those who judged the woman referred in Lk.7:37 could never have released her from the clutches of the evil spirits that had her bound. She received spiritual healing by forgiveness.
+ Un-forgiveness may engender poor health. When faith is present, forgiveness makes the healing process effective. Many times in Scripture, all Jesus offered the infirm was forgiveness, and they were healed Lk.5:20. Clearly there is a strong correlation between forgiveness and healing: ‘Confess your trespasses to one another, and pray for one another, that you may be healed… ‘ Jas.3:16.
* Un-forgiveness ultimately robs one of peace; you cannot be at peace while at loggerheads with another. If your emotions are not involved, your mind is. Peace and harmony are essential to Kingdom life. Apostle Paul to the church in Rome: ‘the Kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost Rom.14:17. The writer of Hebrews counsels thus: ‘Follow peace with all men, and holiness, without which no man shall see the Lord: looking diligently lest any man fail of grace of God: lest any root of bitterness springing up trouble you, and thereby many be defiled… ‘ Heb.12:14-15.
The root of bitterness, the consequence of failure to forgive, defiles.
