Love is the great expression of the oneness God intended when He said, "The two shall become one flesh." One big problem in marriage is selfishness. When we learn to treat our spouse unselfishly - to put our spouse's needs at the center - we begin to love as Jesus does. Divine love is best described in 1 Corinthians 13 and shows us how we should love others. With agape love, marriage can truly be fulfilling and everything God intended it to be.
