The late educator and theologian Herbert W. Armstrong’s successful business had suddenly collapsed—for the second time. To make things worse, his wife challenged him on the Sabbath, and a relative ridiculed him for not believing in evolution. Unlike most of us, Mr. Armstrong was actually willing to extensively prove all things—even if that meant 18-hour days of study for six months straight. To this day, we benefit from his passion for proving and teaching God’s truth.
