When young people marry and refuse to fulfill this commandment given in the beginning of the world [to multiply and replenish the earth] -- and just as much in force today -- they rob themselves of the greatest eternal blessing. If the love of the world and the wicked practices of the world mean more to a man and a woman than to keep the commandment of the Lord in this respect, then they shut themselves off from the eternal blessing of increase. Those who wilfully and maliciously design to break this important commandment shall be damned. They cannot have the Spirit of the Lord.
