I have met someone that I want to be with the rest of my life, but what is the big deal about marriage?

There are many people in America who subscribe to the view of morality called 'cultural ethics'. In other words, the belief that whatever is acceptable in that culture is moral; if the majority of people say a thing is 'right', then it is right. Genuine respect for one another and a lasting caring relationship needs the commitment of sexual faithfulness (one man and one woman for a lifetime) coupled with genuine love . God is the one who established the home and he gives clear instructions on how it can be 'heaven on earth'. But we have to follow His guidelines. STD's (sexually transmitted diseases), divorce, broken homes, shattered lives, and adultery have been a result of men and women who are determined to defy God and struggle against his will for their lives. Hebrews 13:4 states "Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge." The boundaries that God established are not to keep us from happiness, but are to provide us with the greatest possible happiness and protection against harmful and destructive behavior. Since marriage was designed by God, don't you think that he would know best how it could would work for the best interest of ourselves, our children and our society?
