LET'S GET THIS STRAIGHT.
When you take revenge, YOU HAVE NOT FORGIVEN. Forgiving and forgetting are two different thing. It takes the grace of God to forget what evil or offence had been committed against you. Forgiveness is for your own good and it will also help in the healing process. It gives room for divine healing to take place and that will now lead to you forgetting whatever had been done. Yes it is not easy to forget, but that is not the reason why you are carrying out a revenge, it is simply because you still have UN-FORGIVENESS in your heart, you are still holding that person in the bondage of un-forgiveness. Give it all to God today and He will help you all the way and give divine HEALING TO YOUR BROKEN HEART.......
Do not take revenge, my friends, but leave room for God's wrath, for it is written: "It is mine to avenge; I will repay," says the Lord... Rom 12:19.
