Father in heaven, please ease the pain of fighting friends. Although you sometimes cause situations to separate us from ones we won't let go of, it is never easy to accept. If you have allowed this situation for a purpose, I ask that you reveal this purpose to our prayer guest. Allow them to see what is your will, and to find comfort in your guidance. If this friendship is meant to continue, Father, please send your sweet Spirit to make a peace between them so that both sides can see that all true friendships do not end, only heal. Father, please help to forgive hurtful words, heal broken hearts, and allow the truth to be revealed. In Jesus name I pray, AMEN 

Lord, I bring this situation to you. Friendships are truly valuable and I thank you for this one. I pray Father that you would heal both parties hurts at this time, through the miscommunication and open the channels of blessing afresh today. Father, give each an ability to forgive the other, and strengthen their relationship I pray. In Jesus Name. Amen.
