My main point is simple: If your marriage is going to make God look glorious, then you must find more satisfaction in God than in your marriage.
The assumption behind the topic and behind the main point is that God is ultimate and marriage is not. God is the most important reality in the universe. Marriage is less important — far less important, infinitely less important. God is unimaginably great and infinitely valuable and unsurpassed in beauty. “Great is the Lord, and greatly to be praised, and his greatness is unsearchable” (Psalm 145:3).
Therefore, God is absolute reality. We are not. The universe is not. Marriage is not. We are derivative. The universe is of secondary importance, along with everything in it. The human race is not the ultimate reality nor the ultimate value nor the ultimate measuring rod of what is good or what is true or what is beautiful. God is. God is the one ultimate absolute in existence. Everything else exists by him and for him.
