Do you remember what God's first command to humanity was? That first command to his image-bearers wasn't about sin or work or holiness... or even worship. You'll find the first command in Genesis 1:28... "Be fruitful and multiply."
The whole command is: "Be fruitful and multiply and fill the earth and subdue it, and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth."
God was commanding his people to exercise their calling as his image-bearing representatives throughout all of creation! And it is in this specific way -- through childbirth -- that he called us to "multiply" our efforts to serve and honor him -- our Creator -- in every corner of creation.
This is important for Christians to remember, especially in our day of materialism and the enslaving, dominating desire for easy, instant gratification -- in such a setting people are sometimes deceived into thinking that children are more of a hassle than a blessing.
In such a setting birth rates among God's image-bearers might fall farther for longer than at any other time in human history (except for in times of world war or famine). And that's exactly where we are right now.
But no. God's people should not be so deceived.
Listen to Psalm 127: "Behold, children 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."
Give thanks for Brooks! God's work is advancing right before our very eyes.
