“And we know that in all things God works for the good of those who love him, who have been called according to his purpose.”
Romans 8:28 (NIV)
Ask God to bring good from the conflict. God is able to turn the destructive argument into foundations for greater love and understanding. He can bring repentance and renewal to both of your hearts. Entrust the trouble to Him before you decide to give up on your relationship. God can help you to make conflict constructive.
