Genesis 1:26-28 Then God said, "Let us make man in our image, after our likeness. And let them have dominion over the fish of the sea and over the birds of the heavens and over the livestock and over all the earth and over every creeping thing that creeps on the earth." 27 So God created man in his own image, in the image of God he created him; male and female he created them.28 And God blessed them. And God said to them, "Be fruitful and multiply and fill the earth and subdue it and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth."
Genesis 2:15, 23-25 The LORD God took the man and put him in the garden of Eden to work it and keep it.
23 Then the man said, "This at last is bone of my bones and flesh of my flesh; she shall be called Woman, because she was taken out of Man." 24 Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh. 25 And the man and his wife were both naked and were not ashamed.
People are different from animals. God created man and woman in His image. Books are written on what it means to be created in the image of God, but one thing is crystal clear. People are distinctly different from the rest of creation. Man was created to have fellowship with God and to rule over all of creation. People do things by thinking. Animals act according to instinct. We are to value people more than the rest of creation. Men and women are created in God's image and are equal in value.
God created marriage to be between one man and one woman. The marriage was to be of the greatest intimacy and without shame. God commanded that the man and woman were to be fruitful and multiply and fill the earth. The man was to work the garden and the woman was to bear the children. Although of equal value, the man and woman had different roles.
What we are to practice from learning how God created. We are to always value people and their needs over animals and their needs. We are make sure marriage is between one man and one woman. We are to have children and fill the earth. We are to recognize that the Lord created men and women different in order to properly fulfill different roles in marriage.
