Every kind of life has a law—a natural power with a certain tendency and activity. In Romans 7 and 8 the apostle Paul speaks of three laws, which correspond to three lives: the human life, the satanic life, and the divine life. In this booklet, compiled from Life-study of Romans, Witness Lee explains these three lives and laws that operate in every believer. The secret of the Christian life, he shows, is to activate the right life with the right law.
