Proverbs 20:22 Do not say, I will repay evil; wait for the Lord, and he will deliver you. #Bible
Our natural instinct is to react when we are wronged, its seems deeply imbedded within us. To retaliate seems to satisfy all of our emotions at the time. Interestingly though we usually feel regret or even guilt afterwards. The problem with this is that our retaliation drives us even further from the possibility of reconciliation.
Waiting for the Lord Jesus insures the outcome which is truly what we need, and we don't do those things that cause us regret or guilt.
God who knows our hearts, He knows exactly what we need, and He is the only One who can deliver us with the best outcome.
There is another side to this concept of waiting on the Lord. We get to watch God work in our lives. We get to see Him cause those who wronged us to surprisingly apologize, or even get what's coming to them. Jesus might even heal our hearts, or give us wisdom in what is right. Our Lord in dealing with them might even take us from hurt and anger to actually praying for those who have wronged us, asking Him to let them go or stop dealing with them so harshly. I have had this happen in my life, to go from hating them to asking God to stop, yes its weird, but the lesson wasn't for them, but for me.
Rom 8:28 ISV And we know that for those who love God, that is, for those who are called according to his purpose, all things are working together for good.
