There is no room for unforgiveness in the life of the Soldier of The Cross.
Moreover, the Word teaches that unforgiveness blocks the prayer life and makes an opening for the enemy.
Without realizing it, many hold a grudge for the way something has made them feel, rather than for the thing that actually happened. So, because the feeling is so intense that it is impossible to foresee leaving it behind, unforgiveness settles into a riverbed of the thought life and seals off the power of the Holy Spirit in the Believer.
Forgiveness happens in prayer. It's a matter of taking God at His Word, telling Him so, and being willing to lay the matter down. This might need to happen over and over. Maybe even seventy times seven.
We serve a Lord who heals. We serve One who has told us to cast all our cares on Him. That means He will receive us, listen and respond.
Forgiveness is not about acting like nothing happened. It is not about feeling healed. Forgiveness is a step taken by faith, so that the The One who holds the stars in place is free to heal us and do His deepest Work.
Tell Him. Aloud.
