The principles of God's law are contained in the two precepts:

The principles of God's law are contained in the two precepts, "Thou
shalt love the Lord thy God with all thy heart, and with all thy soul,
and with all thy strength, and with all thy mind; and thy neighbor as
thyself."  When we realize this, there will be a searching after truth,
a deep conviction of the far-reaching claims of God's law.

That law takes cognizance of the thoughts of the heart, as well as of
the actions of the life.  A man may be a lawbreaker in heart, yet if the
outward action is wanting, he is treated as loyal by the world.  He may
in heart be an adulterer, yet by his fellow men he may be regarded as
possessing great integrity.  But God's law looks into the secrets of the
heart, and pours a flood of light on things that have been buried in
darkness.  Why, then, do not the teachers of the people search for truth
as for hidden treasure?  Why do they not humble their souls in the dust,
lest they be deceived, as were Adam and Eve in Eden?
