“Fools make a mock at sin” (Proverbs 14:9).
I am not endorsing or promoting George Swinnock as a true Christian when I quote from him. But I think he writes some things that true Christians could benefit from. Swinnock writes:
“… the sober sort of them seemed to hate and abhor that harlot vice, though presenting herself upon a stage with her painted face, and most gaudy dress, which many among us love and like, and even doat [dote–CD] upon her; but such must know that sins in jest will bring at last sufferings in earnest” (Swinnock, Works).
Sins in jest are condemned by Scripture (Ephesians 5:4), and while true Christians may fall into and repent of such sins, it is impossible for them to be characterized by these sins.
“Now to Him being able to keep you without stumbling, and to set you before His glory without blemish, with unspeakable joy; to the only wise God, our Savior, [be] glory and majesty and might and authority, even now and forever. Amen” (Jude 1:24-25).
Proverbs 10:23 says:
“To work out evil devices [is as] laughter to the foolish; so wisdom [is] to a man of understanding” (LITV).
“[It is] as sport to a fool to do mischief: but a man of understanding hath wisdom” (KJV).
To consider evil a tremendous trifle is not enough for these fools; they must further laugh and make sport of that which not only will bring the wrath of God upon the sons of disobedience, but such mockery is a manifestation and revelation of God’s wrath and righteous judgment.
“Then put to death your members which [are] on the earth: fornication, uncleanness, passion, evil lust, and covetousness, which is idolatry; on account of which things the wrath of God is coming on the sons of disobedience, among whom you also walked at one time, when you were living in these. But now, you also, put off all [these] things: wrath, anger, malice, evil-speaking, shameful speech out of your mouth. Do not lie to one another, having put off the old man with his practices, and having put on the new, having been renewed in full knowledge according to [the] image of the [One] creating him” (Colossians 3:5-10).
“For God’s wrath is revealed from Heaven on all ungodliness and unrighteousness of men, holding the truth in unrighteousness, because the thing known of God is clearly known within them, for God revealed [it] to them. For the unseen things of Him from [the] creation of the world are clearly seen, being understood by the things made, both His eternal power and Godhead, for them to be without excuse” (Romans 1:18-20).
More from Swinnock:
“Men laugh, jest, and mock at sin. ‘It is sport to a fool to do mischief,’ Prov. x. 23, but surely they will find hell a serious thing, for ‘God will not be mocked.’ They pretend now that they have time to spare, and if they should not spend it at a playhouse — I had almost said a whorehouse — they should spend it worse” (Swinnock, Works).
I think “playhouse” is probably the place where the plague of porneia was acted out upon the stage (in what I suppose were called, “stage plays”).
