Manasseh the king was a ringleading sinner, the great idolater, and chief of devilism. The whole land flowed with wickedness, “for he made them to sin” and to do worse than the heathen that dwelt round about them. But when God converted him, the whole land was reformed. Down went the groves, the idols, and altars of Baal, and up went true religion in much of the power and purity of it…The king reformed by [royal] power, and by example too (II Chron. 33; II Kings 17:41).
When God takes hold of the hearts of the most notorious, this would make hell to sign, to the great suppression of sin, the glory of Christ, and the joy of the angels of God.
—John Bunyan “The Jerusalem Sinner Saved.”
