God Based His Organization on Family, giving His first command in Genesis 1:28.

Genesis 1:26. Then God said, “We will make mankind in our image, after our likeness and have dominion over the fish of the sea, over the fowl of the air, over the cattle, over all the earth, and over every creeping thing that creeps upon the earth.” 27. So God created mankind in His own image; He created him in the image of God. He created them male and female. (Matt. 19:4) 28. And God blessed them and God said to them, “Be fruitful! Multiply! Fill the earth! Subdue it and have dominion over the fish of the sea and over the fowl of the air and over every living thing that moves upon the earth!”
