And God said to him, "I am God Almighty: be fruitful and multiply. A nation and a company of nations shall come from you, and kings shall come from your own body."
Genesis 35:11

In this verse, God repeated to Jacob the command to be fruitful and multiply. The command applies to all mankind, but it is doubly important for God's faithful remnant to be fruitful, both naturally and spiritually. The world needs good people. We can create them by saving the lost or by making babies. Best to do both!
