A married couple’s sex life is often broken because corporate prayer is of little interest to them.  The importance of prayer in a Christian husband and wife’s life cannot be emphasized enough.  A christian couple who goes without frequent corporate prayer is like a soldier who goes into battle without any armor or weapon.  Going without mutual prayer in marriage is like saying, “I don’t need to eat food or drink water today.”  If fish are meant to swim and that is where they optimally function, then where a human functions the best is when they are in deep relational prayer with Christ; and this is reinforced even more within marriage.
