In the early 1500s, Martin Luther said faith in Jesus justifies us. But he also stated that faith should permeate all areas of our lives, including business dealings. Two and a half centuries later, a young man named John Woolman took this to heart as he opened a tailor shop. Due to his commitment to Christian love, he chose not to purchase any cotton or dye supplies that had been produced by slaves. Then he would be able to say, with a clear conscience, that he had lived according to holiness and sincerity in all his dealings (2 Corinthians 1:12).
