“So God created man in His own image; in the image of God He created him; male and female He created them. Then God blessed them, and God said to them, “Be fruitful and multiply; fill the earth and subdue it; have dominion over the fish of the sea, over the birds of the air, and over every living thing that moves on the earth.””
Genesis 1:27-28 NKJV
God’s plan is to expand his kingdom and He does it through His children. He blessed a man and a woman in marriage to have godly offspring and raise them for His glory. Any male can have sex with a female and make children, but it takes a real man and woman to raise children in the Lord. It takes consistency, patience, love and courage. satan hates this because it’s a terror to him and his kingdom.
