In Genesis Chapter 1 verses 27 Scripture teaches that upon God’s initiative He created man; therefore man did not create himself nor come from any other source.
God created man in two sexes: male and female. What was His charge to man? Verse 28: God blessed them; and God said to them, “Be fruitful and multiply, and fill the earth, and subdue it; and rule over the fish of the sea and over the birds of the sky and over every living thing that moves on the earth.”
Clearly male and female mankind had a general goal: be fruitful, in other words have children, and subdue the earth.
In Genesis Chapter 2 however a deeper, personal reason is given for Adam to have a wife. Verse 18: ‘Then the Lord God said, “It is not good for the man to be alone; I will make him a helper suitable for him.”’
Thus you have a two-fold stated purpose of mankind: first, multiply and rule the earth and second companionship. This companionship is discussed in the Scripture in the following way in verses 21-24:
21 So the Lord God caused a deep sleep to fall upon the man, and he slept; then He took one of his ribs and closed up the flesh at that place. 22 The Lord God fashioned into a woman the rib which He had taken from the man, and brought her to the man. 23 The man 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.” 24 For this reason a man shall leave his father and his mother, and be joined to his wife; and they shall become one flesh.
God took from within Adam a rib that He fashioned into a woman signifying the intimacy of the man and woman and then by verse 24 Scripture teaches that in marriage a man and woman are united with this intimacy in mind.
As the natural reflects the Spiritual since it the natural came from the Spiritual then the creation of Eve from Adam reflects the creation of the ‘bride of Christ’ from within Christ signifying the intimacy of Christ with His bride.
From here you can see Christ’s tremendous love for His bride since His bride came from within Himself. You also see why Christ is always head of His bride and why the bride is never His head since the bride came from within Him.
