God Himself noted that “It is not good that man should be alone” (Genesis 2:18). As the three members of the Godhead are united in a relationship of love, so should human beings created in the image of God reflect relationships of love. To be genuinely human is to be relationship-oriented—seeking opportunities to live for others. God was clear that both male and female are created in the image of God (Genesis 1:26-28). Together, man and woman formed humankind. Together they represent the multi-faceted image of God. This interdependent aspect of the image of God is an integral part of the harmony and prosperity of His kingdom on earth. JTL13 6.1
The ideal marital relationship expressed at Creation was for man and woman to form a whole which would be mutually beneficial and complementary, illustrating the social dimension of the nature of humanity. That woman was built by God from the rib of man does not indicate subordination but rather essential equality. Woman is described as man’s “ezer,” sometimes translated as “helper,” the same word used to portray God, who helps human beings (Psalms 33:20). ‘Ezer Cenegdo describes a power like him or facing him as equal. Thus, the companion God created for man, was to be his counterpart, his complement. JTL13 6.2
The function of sexual relations between a man and a woman in marriage should be in the context of commitment, intimacy, and mutual delight. This concept is much broader than just procreation or even recreation. Sexual differentiation helps define our personhood. The profound mystery of two human beings becoming one through the consummation of marriage in sexual relations also illustrates the love of God for His people and the intimacy of His care for the church.
