Marriage takes three to be complete, It's not enough for two to meat, they must be willed in love by love's creator, God above,  Then their love will be firm and strong able to last when things go wrong, because they've felt the heart and soul and mind, and in that love they've found the way to love each other everyday.  A marriage that follows Gods plan takes more than a woman and a man, It needs a oneness that can be only from Christ - marriage takes three.
