And though there are several degrees both of grace and of the discerning of it, some having but little holiness, and some but little discerning of it in themselves, yet the least may afford much comfort to the soul upon justifiable grounds, though not so much as the greater degrees of grace, and clearer discerning of it, may do.
The foundation being thus laid, it must be our next endeavour to build upon it a settled peace of conscience, and quietness of soul; for till we can attain to joy, it is a great mercy to have peace, and to be free from the accusations, fears, and griefs which belong to the unjustified; and peace must be the temper more ordinary than much joy, to be expected in this our frail condition.
Thirdly, Peace being thus settled, we must endeavour to rise up daily into joy, as our great duty and our great felicity on earth; it being frequently and earnestly commanded in the Scriptures, that we "rejoice in the Lord always," and "shout for joy, all that are upright in heart," Psal. xxxiii. 1; Phil. iii. 1; iv. 4; Deut. xii. 12, 18; xxvii. 7. Thus he that "proveth his own work," may have "rejoicing in himself," Gal. vi. 4, "even in the testimony of his conscience," of his own "simplicity and godly sincerity," 2 Cor. i. 12. And this all believers should maintain and actuate in themselves.
Fourthly, With this rejoicing in God, our lawful, natural mirth must be taken in, as subordinate or sanctified; that is, we must further our holy joy by natural mirth and cheerfulness, and by the comforts of our bodies in God's lower mercies, promote the service and the comforts of our souls. And this is the right place for this mirth to come in, and this is the true method of rejoicing.
Direct. IV. Mark well the usefulness and tendency of all thy mirth: and if it be useful to fit thee for thy duty, and intended by thee to that end, (though you alway observe not that intention at the time,) and if it tend to do thee good, or help thee to do good, without a greater hurt or danger, then cherish and promote it; but if it tend to carry thee away from God to any creature, and to unfit thy soul for the duties of thy place, and to carry thee into sin, then avoid it as thy hurt: still remembering that the necessary support of nature must not be avoided by good or bad. A christian that hath any acquaintance with himself, and with the work of holy watchfulness, may discern what his mirth is by the tendency and effects, and know whether it doth him good or harm.
Direct. V. Take heed that the flesh defile not your mirth, by dropping in any obscene or ribald talk, or by stirring up fleshly lust and sin. Which it will quickly do, if not well watched; and holy mirth and cheerfulness is very apt to degenerate on a sudden into sinful mirth.
Direct. VI. Consider what your mirth is like to prove to others as well as to yourselves. If it be like to stir up sin in others, or to be offensive to them, you must the more avoid it in their presence, or manage it with the greater caution: if it be needful to cheer up the drooping minds of those you converse with, or to remove their prejudice against a holy life, you must the more give place to it: for it is good or bad as it tendeth unto good or bad.
Direct. VII. Never leave out reason or godliness from any of your mirth. Abhor that mirth that maketh a man a fool, or playeth the fool: and take heed of that ungodliness which maketh a man merriest when he is furthest from God, like the horse or ox that leapeth and playeth for gladness when he is unyoked or loosed from his labour. Something of God and heaven should appear or be dropped into all our mirth, to sweeten and to sanctify it.
Direct. VIII. Watch your tongues in all your mirth; for they are very apt to take liberty then to sin. Mirth is to the tongue as holidays and play-days to idle scholars; who are glad of them as a time in which they think they have liberty to game, and fight, and do amiss.
Direct. IX. If a word break forth from yourselves or companions to the wrong of others in your mirth, as of backbiting, evil-speaking, jeering, scorning, defaming, (yea, though it be your enemy,) rebuke it, and cast it out, as dirt or dung that falleth into your dish or cup.
