Sexual problems in marriage have many causes, but one of the greatest causes comes from disrespecting the marriage covenant by not knowing the true meaning of it. A marriage covenant involves three concepts. (1) Understanding the marriage vows; (2) Understanding the consummation of those vows through sex and (3) Understanding the meaning of sex, which is, throughout the marriage, commemorating these vows through love making. 

    As we all know, the essence of the marriage covenant is this: "I take you to be my wedded wife/husband, to have and to hold from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, to love and to cherish, till death do us part. This is my solemn vow. According to God's holy ordinance; and thereto I plight you my troth." What is God’s holy ordinance? Jesus stated it plainly when He said "Have you not read that he who created them from the beginning made them male and female, and said, 'Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh'? So they are no longer two but one flesh. What therefore God has joined together let not man separate." (Mat 19:4-6) God’s holy ordinance is that the two become one in marriage and that they stay one. Webster's New Collegiate Dictionary says this of the word, "ordinance"--"That which is decreed or ordained, as by God … an established rite for the administration of a sacrament."
