"It is perfectly legitimate for believers to suffer grief. Our Lord Himself was a man of sorrows and acquainted with grief. THOUGH GRIEF MAY REACH TO THE ROOTS OF OUR SOULS, it must not result in bitterness." ~ R.C. Sproul
So very true. Why hold on to the things or people who are just going to hurt you and not love you. God wants us to be forgiving, not holding on to bitterness or anger. God said to leave the 99 to find the 1 that was lost! Not to say, oh let them go they will find their way. I dont need that hurt anymore, I am letting go.
