Your prayer for deliverance has been heard, and it is a good and right thing to bring the wounds of cruel words and the heaviness of an unforgiving spirit to the Lord Jesus Christ, for He alone is the Deliverer.
The Scripture you have stood upon is true. If the Son shall make you free, you shall be free indeed, John 8:36. Yet remember what we have often taught, that deliverance from the power of sin, and from the sting of sin in others, is as much the work of God as deliverance from the guilt of sin. Where we look for justification, there must we also look for sanctification, for as we are justified through Jesus Christ, we must also expect to receive our healing and our peace from a heavenly source alone. He must bring you forth. You can do nothing and He knows it, and therefore your deliverance must be of Free Grace only.
There is such a thing as sickness of the soul which is far worse than disease of body, when insult and gaslighting and contempt have been spoken over you until you doubt your own soul. Blessed be His name, there is such a thing as recovery from soul sickness even to those who appear to be going down into the pit. God has not only invented a way of deliverance, but He has found a ransom. So it is a gift of Divine Love. Nobody would have thought of that way of deliverance of a sinner from the pit through a ransom if God had not thought of it. That ransom is the precious blood of the Lamb, by which we overcome, Revelation 12:11.
You ask rightly that strongholds should be brought down, for though we walk in the flesh we do not war after the flesh, and the weapons of our warfare are mighty through God to the pulling down of strongholds, 2 Corinthians 10:3-5. The stronghold of offense and unforgiveness is not cast down by binding words alone, but by looking to Christ and learning to forgive as we have been forgiven. To retain offense is to keep yourself in bonds. To loose it by forgiveness in Christ's name is to walk in the liberty wherewith Christ has made us free, Matthew 18:18.
Therefore let us pray together for that true deliverance which is effectual and attended with enrichment.
O Lord our God, who has delivered us from the power of darkness and translated us into the kingdom of Your dear Son, look upon this wounded one. You know the insults spoken, the words meant to tear down and to make the heart doubt. Let those words fall powerless to the ground, for Your word alone shall stand over Your child. We ask that You would lift from this soul every lie that has been received, and speak Your truth in its place, that this one is accepted in the Beloved, not in the esteem of man.
Grant a true pulling down of every stronghold of offense and unforgiveness. Teach this heart to forgive, not in its own strength, but as one who has been forgiven much. Cover this prayer and this life with the precious blood of Jesus, Your found ransom, and let the accuser be overcome. Make this deliverance sure, for You bring Your people forth with Your own hand.
And after this affliction, let this tried one live and declare the works of the Lord, Psalm 118:17. Give grace to dwell much in Your Word, to seek peace within Your borders, and to walk in holiness before You, looking to Jesus Christ alone for all justification and all sanctification.
We ask this not because we are worthy, but because You have found a ransom, and because Christ has promised freedom indeed to those whom He sets free. In the name of Jesus Christ our only Saviour, Amen.
