In Genesis 2:24, when the marriage covenant is ordained, man and woman are designated as "one flesh"—one unit. God is indeed creating a Family modeled after His own characteristics, but not all Godlike characteristics are found in one sex or gender, any more than they are found in one race. It bears repeating that God did not create a superior and inferior sex, any more than He created a superior and inferior race.
God has characteristics (revealed throughout Scripture) that are considered to be masculine and feminine. Our own bodies mirror this. Human reproductive glands, for example, manufacture both male and female hormones. Women's ovaries produce small, but significant amounts of androgen (a male hormone). Likewise, men's testicular canals produce not only testosterone, but also a small but significant amount of estrogen (female hormones). God has also designed the human anatomy so that both sexes have vestigial equipment of the opposite sex. No one is 100% male or 100% female—not even the most muscular man or the curviest woman can claim this distinction.
Together, men and women make up a composite image of the living God. Individually, we are incomplete, partial, and lacking something in our personality. One of the reasons God gave us marriage state (a God-plane relationship) is to learn how the other half of the God-image behaves. We learn from our mate's traits and characteristics of the opposite sex in order to become complete God-beings. The Bruce Willis/Russell Crowe macho-warriors and the Nicole Kidman/Meg Ryan goddess stereotypes are insufficient models for a God-being. God the Father is not in the process of making macho-warriors or goddesses, but balanced members of His Family.
Part of this process—incredible as it sounds—involves the male incorporating Godlike feminine (not effeminate) characteristics such as tenderness, mercy, and patience. Similarly, the female needs to learn or adopt masculine (not tomboy or butch) characteristics such as strength, assertiveness, and decisiveness. If we make a thorough search of the Scripture, we would find the masculine and feminine traits of God equally distributed. Ironically, if gender-neutral advocates had their way, these delightful differences would be blotted out.
Space permits elaboration on only a few from each list. We see ample and abundant masculine traits in the Bible: strength, power, decisiveness, aggressiveness, provider, ruler, and leader. Feminine traits are also abundant: beauty, grace, mercy, tenderness, caring, and affectionate. In order to qualify as members of God's Family, both men and women need to incorporate all these characteristics into their personalities.
Men often have a hard time being as loving and affectionate as their wives are. Little boys know that Mommies make the best pillows, and Daddies make the best armrests. If some of the women in the congregation would enlist the aid of the men in the congregation to hold their babies, the men might break out in a cold sweat. Nevertheless, motherly feelings and instincts come from God. It did not bother Jesus Christ to express a motherly instinct: "O Jerusalem, Jerusalem. . . ! How often I wanted to gather your children together, as a hen gathers her chicks under her wings. . . !" (Matthew 23:37).
