I am confused about where the salvation issues lies. But I trust you know the concerns of your heart, and I trust that God knows what, if any, issues regarding salvation need to be addresse in your daughter-in-laws heart. I can tell you love her, and your son. We want the best for our children, and our grandchildren's salvation is dependant (with reason) on their parents.
Lord, we come before you know asking for peace between mother and daughter. We pray your holy spirit will guide them both, in word and in deed. Lord, where there is unforgiveness let grace be given freely. Relationships are so important!! Lord, help each and every one of us to see the flaws in our own thinking. LEt your holy spirit guide and direct us in a closer, deeper relationship with you lord. Let us not get trapped in the letter of the law, but undstand the spirit of the law. Let us be the followers you desire, those who long to love you and others above all else. Lord, forgive us each and all of our sins. THank you for the blood of JEsus Christ who brings salvation. You are all knowing, all-powerful, gracious, kind and just. THank you for hearing our prayers. in jesus name. amen
