Sin, beginning in the Heart – Charles Spurgeon

PERSONS will dare to profess the religion of Christ who can enjoy a lascivious song and broad talk, who are given to what is softly styled imprudence, which is really impurity. Impure familiarities, glances, and sports, are the commencement of actual crimes. Men and women who in any way injure their delicacy and modesty, by insensible degrees proceed to overt sin. All men wonder when a professor falls into foul sin, but they would not wonder if they knew how long the transgressor had gone to the verge of the precipice; the wonder would be rather that the moth had not burnt its wings in the candle long before. Oh, hate the very thoughts of impurity! Your members are members of Christ, your bodies are to be raised in the image of Christ; defile them not, but walk with the utmost purity as in the sight of the thrice holy God.
