1 Kings 13:33,34

(33) After this thing Jeroboam returned not from his evil way, but made again of the lowest of the people priests of the high places: whosoever would, he consecrated him, and he became one of the priests of the high places. (34) And this thing became sin unto the house of Jeroboam, even to cut it off, and to destroy it from off the face of the earth.

What an awful example doth this man afford of an unreclaimed heart! oh, Reader! learn from it the vast and infinite importance of the Spirit's work upon the soul, without whose gracious influence every sinner's heart would be more and more hardened, through the deceitfulness of sin.
