10. Another is, ostentation or proud boasting, either of men's wit and learning, or greatness, or riches, or honour, or strength, or beauty, or parts, or piety, or any thing that men are proud of.[481] As the faithful "do make their boast in God," Psal. xxxiv. 2; xliv. 8, and in the "cross of Christ," by which "they are crucified to the world," Gal. vi. 14; so the covetous "boast themselves in the multitude of their riches," Psal. xlix. 6, and the "workers of iniquity boast themselves against the righteous, and the proud do triumph and speak hard things," Psal. xciv. 2-4. "Even against the Lord," do they boast, in their boasting against his people, Ezek. xxxv. 13. So far as pride prevaileth with men, they are apt to "boast themselves to be somebody," Acts v. 36. Either openly, as the more foolish do, or cunningly by the help of fair pretences, as the more ingenious proud ones do.
11. Another sin of the tongue is, unseasonable speaking of common things when holy things should be preferred; as on the Lord's day, or at the time of public worship, or when the company, occasion, or opportunity call for holy speeches: worldlings are talking, as Saul, of their asses, when they should talk of a kingdom, 1 Sam. ix. x. To speak about your callings and common affairs is lawful, so it be moderately and in season; but when you talk all of the world and vanity, and never have done, and will scarce have any other talk in your mouths, and even on God's day will "speak your own words," Isa. lviii. 13, this is profane and sinful speaking.
12. Another common sin of the tongue is, a tempting and persuading others to sin, enticing them to gluttony, drunkenness, wantonness, fornication, or any other crime; as men that "not only do the same, but have pleasure in them that do them," Rom. i. 32. This is to be the instruments and servants of the devil, and most directly to do his work in the world. The same I may say of unjust excusing, extenuating, or defending the sins of others, or commanding, alluring, affrighting, or encouraging them thereto.
13. Another is, a carnal manner of handling the sacred things of God, as when it is done with lightness, or with unsuitable curiosity of words, or in a ludicrous, toyish manner, especially by the preachers of the gospel themselves; and not with a style that is grave and serious, agreeable to the weight and majesty of the truth.
14. Another is, an imprudent, rash, and slovenly handling of holy things; when they are spoken of so ignorantly, unskilfully, disorderly, or passionately, as tendeth to dishonour them, and frustrate the desired good success.[482]
15. Another sin of the tongue is, the reviling or dishonouring of superiors; when children speak unreverently and dishonourably to or of their parents; or subjects of their governors; or servants of their masters, either to their faces, or behind their backs. "They are not afraid to speak evil of dignities," 2 Pet. ii. 10; Jude 8.
16. Another is, the imperious contempt of inferiors, insulting over them, provoking and discouraging them. Eph. vi. 4, "Fathers, provoke not your children to wrath."
17. Another sin of the tongue is, idle talk and multitude of useless words; a babbling loquacity, or unprofitableness of speech; when it is speech that tendeth to no edification, nor any good use for mind, or body, or affairs.
18. Another sin is, foolish talk, or jesting in levity and folly, which tendeth to possess the minds of the hearers with a disposition of levity and folly like the speakers. Eph. v. 4, "Foolish talking and jesting are things not convenient." Honest mirth is lawful; and that is the best which is most sanctified, as being from a holy principle, and about a holy matter, or to a holy end: as "rejoicing in the Lord always," Phil. iv. 4. "If any be merry let him sing psalms," James v. 13. But such a light and frothy jesting, as is but the vent of habitual levity by idle words, is not allowable. But especially those persons do most odiously abuse their tongues and reason, who counterfeit idiots or fools, and use their wit to cover their jests with a seeming folly, to make them the more ridiculous, and make it their very profession to be the jesters of great men. They make a trade of heinous sin.
19. Another sin is, "filthy speaking," Eph. v. 4; obscene and ribald talk; which the apostle calls "corrupt or rotten communication," Eph. iv. 29; when wanton, filthy minds do make themselves merry with wanton, filthy speeches. This is the devil's preparative to whoredom and all abominable uncleanness; for when the tongue is first taught to make a sport of such filthy sins, and the ear to be delighted in it, or be indifferent to it, there remaineth but a small step to actual filthiness.
