Genesis 1:24-31

24 Then God said, “Let the earth bring forth living creatures after their kind: cattle and creeping things and beasts of the earth after their kind”; and it was so.

25 God made the beasts of the earth after their kind, and the cattle after their kind, and everything that creeps on the ground after its kind; and God saw that it was good.

26 Then God said, “Let Us make man in Our image, according to Our likeness; and let them rule over the fish of the sea and over the birds of the sky and over the cattle and over all the earth, and over every creeping thing that creeps on the earth.”

27 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 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.”

29 Then God said, “Behold, I have given you every plant yielding seed that is on the surface of all the earth, and every tree which has fruit yielding seed; it shall be food for you;

30 and to every beast of the earth and to every bird of the sky and to every thing that moves on the earth which has life, I have given every green plant for food”; and it was so.

31 God saw all that He had made, and behold, it was very good. And there was evening and there was morning, the sixth day.

Quotes:

“Men are not women.  Women are not men.  One of the saddest things in the universe is a man who tries to be a woman or a woman who tries to be a man. ‘But who is superior?’ someone asks. 

I answer.  A man is absolutely superior to a women—at being a man; a woman is absolutely superior to a man—at being a woman.  But let a woman try to be a man or a man try to be a woman, and you have a monstrosity.” (Dr. James Montgomery Boice) 

“This implies that human sexuality is of a different sort from animal procreation: human procreation is not intended merely as a mechanism for replication or the expression of human passion but is instrumental in experiencing covenant blessing.  The union of man and woman as husband and wife is an inclusive oneness.  Human life, unlike the lower orders, is not instructed specifically to reproduce “after its kind.” 

This omission elevates the sexual experience and goal of the human family as distinctive.” (Kenneth A. Mathews)
