We pray that you will allow healing and reconciliation to take place, that whatever hurts or disappointments they have experienced can be mended through the power of your undying eternal Love and your precious HOLY SPIRIT!
We realize Father that they cannot change anything that has happened but, they can go forth together keeping, renewing and, once again, honoring their vows.
Father. we realize that much spiritual warfare is about them. We realize that it wants to divide and separate them. We ask Lord that they invite you into the messiness to bring about order! Lord, we realize that ALL of your promises are true. We ask that you endow them with the necessary strength and wisdom to endure.
We pray all this in the name of Jesus.
