The Bible tells us the truth about marriage. Man and woman. It goes right up there with all the other opposites. Day/night, beginning/end, light/darkness, good/evil etc. I can go on but you see the point. God made marriage holy between a man and woman and sanctified it. Holiness is the opposite of sin. When two opposite sinners are joined together by marriage it exposes sin because of the holiness of the Union. If things are made the "same" it goes against the nature of God. Sin is not exposed. My wife exposes the sin in my life. It is for me to change. Example. Apathy is a sin. If I do not think our marriage is worth fighting for I go the Word and I see a marriage that someone died for. Jesus Christ and his bride the Church. In a world that wants instant pleasure it is no surprise of the mess we are about to experience.
