For the day of the Lord draws near on all the nations. As you have done, it will be done to you. Your dealings will return on your own head. Obadiah 1:15
We are each responsible for our own actions and words. We will not be penalized for the actions of others, but we will be held accountable for our own actions and words. God sees everything we do and hears everything we say, and we are so blessed that we have an awesome forgiving God, but we must be willing to drop the pride and admit our wrong doing in order to be forgiven. That includes the wrong of not forgiving others.
It is time to forgive those who have hurt you and love them the way God desires you to. There are times when it is extremely difficult to forgive when we have been hurt so very badly, but we will not be able to learn and grow in love unless we do. What is past will always be a part of you, but you can use that event to help another. Trust that God will heal the wounds and take that burden off your heart and forgive.
