“Just and True”

Joseph F. McConkie, Robert L. Millet
That which is “just” is that which is “right.” Thus the justified are those who have done that which is right and proper in the eyes of God, or whose lives have been made right through the mediation of a greater power. That which is “true” is that which is “faithful” or “trustworthy.” To be brought to a knowledge of that which is “just and true” is to come to that knowledge which marks a straight course, one which can be followed with full confidence and trust.
