Rev. R. Albert Mohler, Jr., the president of Southern Baptist Theological Seminary, says it's "an absolute revolt against God's design" if husbands and wives purposely avoid bearing children.

On his Web site and other articles and interviews, Mohler argues that "marriage, sex and children are part of one package" and that "to deny any part of this wholeness is to reject God's intention in creation and his mandate revealed in the Bible."

In a CNN interview, the Baptist leader added, “We grow up by having children. Without that responsibility, we have a generation of perpetual adolescents just growing old."
