Guilt is the Holy Spirit’s way of telling you that you screwed up. Listen to It.
I do.
Amen.
It can also be called a "well formed conscience".
Absolutely correct: Listen to it.
I would beg to differ.
Conviction of sin is from the Holy Spirit. Guilt is both what we feel over it and what Satan beats us over the head with even after we have repented and asked and received cleansing from that sin.
Yes, we should feel bad about sin, but with godly sorrow, which leads to repentance.
2 Corinthians 7:9-10 As it is, I rejoice, not because you were grieved, but because you were grieved into repenting. For you felt a godly grief, so that you suffered no loss through us. For godly grief produces a repentance that leads to salvation without regret, whereas worldly grief produces death.
I once preached a sermon that was basically “Guilt is that thing that says ‘Man, I wouldn’t do that stuff again if I was you’”.
