Lest these hypocrites should pretend that their hearts were not departed from God, or should say, Who then can judge us if none knoweth the heart? saith God, Though no creature knoweth the heart of another fellow creature, yet I know the hearts of all creatures, I search the secret thoughts, and counsels, and designs of all my creatures; for I will judge them according to their thoughts and the secret motions and affections of their souls, according to all their ways, and the fruit of their doings. You cannot therefore mock me, and tell me your hearts are not departed from me.
