Written on their hearts
And thus it is, that the law of God is now made known to those who do not know God. They hear, with the hearing of the ear, the things that were written aforetime for our instruction. But this does not suffice. They cannot by this means comprehend the height and depth and length and breadth of it. God alone can reveal this by his Spirit. And so he does to all that truly believe, in consequence of that gracious promise, made to all the Israel of God: Behold, the days come, says the Lord, that I will make a new covenant with the house of Israel. And this shall be the covenant that I will make, I will put my law in their inward parts, and write it in their hearts, and I will be their God, and they shall be my people. (Jeremiah 31:31).
