“And God blessed them, and God said unto them, Be fruitful, and multiply and replenish the earth, and subdue it…” Genesis 1:28 KJV
In Mark Steyn’s book, America Alone he does extensive research on the demographic changes in our world. According to Steyn; “as fertility dries up, so do societies. The single most important fact about the early twenty-first century is the rapid aging of almost every developed nation other than the United States.” The replacement fertility rate—i.e., the number you need for merely a stable population, not getting bigger and not getting smaller–is 2.1 babies per woman. America is just at 2.1 percent and only so because of our Hispanic population.
Some countries are well above that. The global fertility leader, Niger, is 7.46; Mali, 7.42; Somalia, 6.76; Afghanistan, 6.69. What do each of these nations have in common? They are all Muslim!
It is amazing that God instructed His Covenant people to keep multiplying and fill the earth. He not only desired that we physically populate the earth but that we would be carriers of His truth to the whole world. The easiest way would be to have enough people to carry that message just like the Muslims are presently doing.
Once again the wisdom of Yahweh God from the book of Genesis has radical application and profound implications for us today!
