The result is the contamination of the home that leads to its destruction. We need to ask what is God's ideal regarding marriage and then get back to it. No philosopher or marriage counselor is going to help us if we leave God, who created marriage and the home, out of its restoration. Marriage is for the comfort, pleasure, and happiness of the Creator's people. She is good for him because she was created that way.
Marriage is for the comfort, training, and security of children.
Marriage is to fulfill the sexual desires of men and women. Marriage is to perpetuate the human race. The idea of surrogate mothers would destroy the home if carried to its logical implications. God's ideal home and marriage involve one man and one woman. The creation of only one of each sex implies this.
