Pray that God might help you overcome it, replacing it with love. Lord, it is not easy getting along with others, especially those closet to us. Things are said and done, or left unsaid or not done that really hurt. They are difficult to ignore or get over. Not easy to love our neighbor, Lord.
Grudges grow so easily in our hearts.
Soon they leave room for nothing else. Weed the grudges out of my heart, O Lord. Replant there the seeds of love.
