Forgiveness doesn't necessarily mean you can no longer be angry. It definitely doesn't mean you need to forget what happened. (Anger can be a righteous thing and remembering helps us understand how God helps us through bad things.)
Don't allow the enemy to lie to you; trying to convince you that "forgiveness" mean forgetting & no longer being angry. ("Be angry; but sin not!")
I wish eternal damnation on NO MAN. But, that doesn't mean "judgment" & "justice" should not be carried out. (That brings me to another lie the enemy tells us an many believe.)
Christians are called to be judges of sinful behavior. We are given the task to judge & pass sentences on illegal & sinful behavior. In fact, one day we will sit in judgement along with Christ has lost souls pass before HIM.
But, we are supposed to handle this difficult task without hatred or malice. Therein lies the "rub"; and the challenge. The only way possible to forgive, yet judge & pass sentence without any HATE or Malice against our enemies is to do so under complete control & direction of the Holy Spirit. (Otherwise, we judge & pass sentence from a state of SIN.)
It's important to understand, when we do anything from the state of "sin"
, we run the real risk of stepping out of Gods grace & HIS hand of protection.
Sorry for the preaching.
