The dread and terror of God entered by sin; Adam had not the least thought of hiding himself until he had sinned. The guilt of sin being on the conscience, and this being a common notion left in the hearts of all, that God is a most righteous revenger thereof; this fills men with dread and horror at an apprehension of his presence, fearing that he is come to call their sins to remembrance. Now, the Lord Jesus, by the sacrifice and the atonement that he hath made, hath taken away this conscience of sin; that is, a dread of revenge from God upon the account of the guilt thereof. He hath removed the slaying sword of the law, and on that account gives us great boldness with God; discovering him unto us now, no longer as a revenging Judge, but as a tender, merciful, and reconciled Father.
