Can a population get too big? This verse would seem to say “no”, although this is certainly not a “proof text.” One of the websites I have seen is called “Zero Population Growth”. There are a mound of people who think there are already too many of us on this planet and more are on the way. Part of their thinking is the people are pollution and a threat to Mother Earth. Whether they know it or not they are Gaia worshipers.
God reminds us that population growth is a good thing. He tells us to glory in our children.
(Psalms 127:3-5 KJV) 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.Some are not physically able to have children. Some have the gift of singleness and a calling that does not allow children. God will honor them in other ways.
So glory in the children if you have them. Invest your life making them into servants of God. If you have none then celebrate with those who do.
