When a man believes in Jesus Christ he puts away his false gods, and worships the great Father of spirits; he makes no inferior object the aim of his being, but henceforth lives for the glory of God. This is a glorious turning, a complete conversion of the man’s heart and soul.

To turn to God means not merely to forsake the false god for the true, but to turn from the love of sin. Sin lies that way, but God’s glory lies in the opposite quarter. He who looks sinward has his back to God — he who looks Godward has his back to sin. It is blessed conversion when men turn from the folly of sin to the glory of God. With weeping and supplication do men so turn, confessing their wrongdoing, lamenting their transgressions, abhorring their evil lustings, desiring pardon, and hoping for renewal of their nature. Precious in the sight of the Lord are the tears of penitence and the sighs of contrite hearts. We can never be satisfied with the results of our ministry unless faith leads man to hearty repentance towards God, an intense loathing of their sins, and an actual forsaking of them.
