It is the existence of opposites coupled with the agency of man that gives meaning and purpose to our moral probation. Laws are essential to the purposeful life, as is a clear distinction between good and evil. Any therapy that purports to free men from the burden of sin by denying the existence of sin also denies to its adherents that joy and peace which can only be known by obedience to the laws of God. Any religious system in which a profession of faith is accepted as a substitute for true repentance denies its practitioners not only relief from the burden of sin but also the very knowledge of how one obtains God's favor and progresses in the direction of the divine presence.
