Basic fundamentals are foundational to virtually everything in life. For example, complex computer systems operate using primarily 1’s and 0’s. Baseball is mainly pitching, hitting, and fielding, and even football can be understood using X’s and O’s. Even so, none of these examples reach maximum potential until every fundamental aspect is working together. God designed marriage no differently. Things like communication, sex, conflict management, finances, and Spirituality are each fundamental aspects of marriage, but any couple married for decades will tell you it’s only when they all work in unison that real joy and oneness can be experienced.
