Children are not a disease, hassle or distraction. Not even a necessary evil. They are a lasting reward for our efforts and gift from God himself.
Contrary to modern sensibilities, a large family is a blessing. Think about the blessing your current family is. It can be more. God is encouraging more children for his people. Obviously we’re all limited and so should our family be. But when weighing out the cost of another child consider the blessing will be even more than you can imagine.
A quiver full of arrows is meant to be emptied. Don’t empty is aimlessly.
