My children are my greatest treasures in this life after Jesus Christ. Invest into them wisely. This is storing your treasures in heaven.

Lo, children are an heritage of the Lord: and the fruit of the womb is his reward. As arrows are in the hand of a mighty man; so are children of the youth. Happy is the man that hath his quiver full of them: they shall not be ashamed, but they shall speak with the enemies in the gate.
Psalm 127:3-5
