We will know by this that we are of the truth, and will assure our heart before Him in whatever our heart condemns us; for God is greater than our heart and knows all things. (1 John 3:19â20)Every human being is born with the law of God written in the heart and with a conscience to accuse or excuse, depending on how the person acts in regard to that law:For when Gentiles who do not have the Law do instinctively the things of the Law, these, not having the Law, are a law to themselves, in that they show the work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them. (Rom. 2:14â15) . . .
