I think I have dealt with this, and then a name or a memory comes up and the resentment is right there again. How do I actually get free?

“Thus my heart was grieved, and I was pricked in my reins. So foolish was I, and ignorant: I was as a beast before thee.”

Asaph was a temple musician, and he wrote this after watching people who cheat do very well while he kept his own hands clean. He describes his soured heart with unusual bluntness, calling himself foolish and beastlike. What changes is not his circumstances but where he goes: into the sanctuary, where the whole picture looks different. He does not talk himself out of it, he worships his way through it.

“Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;”

Paul is defending his ministry against critics in Corinth, and reaches for siege imagery: strongholds, arguments, thoughts taken prisoner one at a time. The picture assumes a fight that repeats rather than one that is won and over. Thoughts get captured in the moment they show up. That is slower than deliverance, and considerably more realistic than pretending the thought never comes.
