Hang on to God's Lips - Calvin's Institutes 8

John Calvin:

"...it is to be observed, that the first man revolted against the authority of God, not only in allowing himself to be ensnared by the wiles of the devil, but also by despising the truth, and turning aside to lies. Assuredly, when the word of God is despised all reverence for Him is gone. His majesty cannot be duly honored among us, nor his worship maintained in its integrity, unless we as it were upon his lips." Institutes of Christian Religion, Book II, Chapter I, 213.

Active sinfulness comes from passiveness toward God's Word. If you are not hanging onto the lips of God sin will follow quickly. It's not enough to simply assume God's Word, one must pursue it, otherwise lies will become more attractive and the Devil will gain more power. To fight against the Devil, like Jesus showed us, is to hang onto the lips and words of God.
