1. Creation mandate to become one flesh, be fruitful and multiply and fill the earth.
2. Marriage is a covenental union before God that images Christ and His Church. To abdicate responsibility and covenent commitment by simply living together or thinking that we can enjoy the benefits of marriage without the responsibilities (I.e. casual sex) is fiat thinking.
3. Children need a mother and a father who are covenentally committed to one another and who establish an anti fragile and missionally aligned house hold.
4. Marriage and children are the bedrock of any civilization. Developed a low time preference, think generationally. Build a legacy. "A good man leaves an inheritance to his children’s children" Proverbs 13:22.
5. Devils and tyrants hate marriage and children, they despise human flourishing and productive households, they loath self sovereignty and liberty.
Marry, be faithful to your spouse, have children and train them up in the fear and admonission of the Lord, and in good and virtuous living. "Behold, bchildren are a heritage from the LORD, the fruit of the womb a reward. Like arrows in the hand of a warrior are the children of one’s youth. Blessed is the man who fills his quiver with them! He shall not be put to shame when he speaks with his enemies in the gate" Psalm 127:3–5.
