One of the things that can help very different spouses the most (in conflict resolution) is growth in God's Word. The more we have God's Word in common as husbands and wives, the more we will agree. The more each mind is renewed (changed) by the Scripture, the more similarly a couple will think (Romans 12:2). One of the worst things a couple can do is work to change one another into each other's likeness. They are to be changed, rather, into Christ's likeness. The more a couple works at love and becoming one, the more differences will be accepted and blended to enhance the marriage.
