“Today the cry is heard in some quarters that these statements calling upon parents to provide bodies for the spirit hosts of heaven are outmoded. Massive birth control programs are being sponsored on a national and international scale. Fears are expressed that the earth cannot support the number of people that unrestricted births will bring. But God’s decree and the counsel of the prophets remain unchanged. The real need is not to limit the number of earth’s inhabitants, but to learn how to care for the increasing hosts which the Lord designs should inhabit this globe before the last allocated spirit has been sent here to gain a mortal body. Amid all the cries and pressure of the world, the position of the true Church remains fixed. God has commanded his children to multiply and fill the earth, and the earth is far from full.”
