“I can no longer condemn or hate a brother for whom I pray, no matter how much trouble he causes me. His face, that hitherto may have been strange and intolerable to me, is transformed in intercession into the countenance of a brother for whom Christ died, the face of a forgiven sinner.” ―Dietrich Bonhoeffer
Prayer, real prayer, is not only hard work; it is transformative! As you sincerely pray for them, you find love for them despite the trouble between you. Real prayer moves the mountains in your heart. If I am still angry or bitter about how someone wronged me or others, I know *I* need to humbly go back to the Lord and work it out with Him by praying for that person like I would pray for myself.
