In the very first Chapter in the very first book of the Bible, God reveals himself and his purpose in creation.
In the original Hebrew text, the word for God in this chapter is Elohim - Creator and Judge. "In the beginning, God (Elohim) created the heavens and the earth." Genesis 1:1 Elohim is a plural noun referring to a single nature of divinity -- the plurality within the Godhead. God the Father, the Son of God and the Holy Spirit are in unison of power and purpose when they created the heavens and the earth. No disagreement, no quarrels and no hierarchy. Although Jesus takes his authority from God the Father, He is not less important. He works in unison of purpose just as the Holy Spirit works in unison in purpose. Individually their nature compliments the others so perfectly that together they become one.
Elohim creates on day 6 the grand finale of creation:
26 Then God said, "Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, [b] and over all the creatures that move along the ground."
27 So God created man in his own image, in the image of God he created him; male and female he created them.
28 God blessed them and said to them, "Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground."
After the grand finale, "God saw every thing that he had made, and behold, it was very good. (v31)" This is the end of the sixth day. The seventh day God rested and blessed creation.
It isn't until Chapter 2 that God created a physical body for both Adam and Eve.
7-8And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul. And the LORD God planted a garden eastward in Eden; and there he put the man whom he had formed.
15And the Lord God took the man, and put him into the garden of Eden to dress it and to keep it.
18And the LORD God said, It is not good that the man should be alone; I will make him an help mate for him.
21-24And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof; And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man. And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man. For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh.
Elohim created our nature or spirit -- both male and female -- on day 6. After the seven days, God then created the flesh in chapter 2 and breathed His life into Him and became alive. He gave us purpose before flesh.
Elohim also displays a pattern for communicating with His creation. He gives us purpose and then personally confirms it. In 2:15 the Lord God, in perfect harmony of relationship, confirms the man's purpose. He also lets Adam know he is incomplete by himself. Remember that a help mate was already prepared in chapter one. God does not forget anything. He creates a woman out of the man's rib while he sleeps and then presents the woman to the man. Immediately Adam recognizes her as a part of himself.
Both male and female were made in God's image, in God's likeness. In a marriage, male and female are united to become one flesh, to complement each other in purpose. Male and female need each other and will be incomplete without the other. If they separate, they must compensate for the loss. Jesus confirms this in Matthew 19:4-6 and Mark 10:6-9 (quoted below is Matthew):
4"Haven't you read," he replied, "that at the beginning the Creator 'made them male and female,'[a] 5and said, 'For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh'[b]? 6So they are no longer two, but one. Therefore what God has joined together, let man not separate."
Men and woman were created in unison of purpose for creation with God as the third. Neither should dominate the other. One is not less than the other. Even the feminine nature is created in God's image. Is not our Lord like a new born mother who provides for our security, the mother listening to their babies cries and provides for their needs? Does not our Lord watch over us as we grow in Faith, learning to trust Him? He watches over us as we sleep, counting our hairs. I have seen many a mother do this as they hold their sleeping baby in their arms. God intended for us to respect each other, not compete with each other. Marriage is part of God's plan and designed from the beginning. To work together to accomplish God's plan for each other and His creation.
