The concept of family is extremely important in the Bible, both in a physical sense and in a theological sense. The concept of family was introduced in the very beginning, as we see in Genesis 1:28, “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.'” God’s plan for creation was for men and women to marry and have children. A man and a woman would form a “one-flesh” union through marriage (Genesis 2:24), and they with their children become a family, the essential building block of human society.
