§ 18. Little do we know how we wrong ourselves by shutting out of our prayers the praises of God, or allowing them so narrow a room as we usually do, while we are copious enough in our confessions and petitions. Reader, I entreat thee, remember this, let praises have a larger room in thy duties; keep matter ready at hand to feed thy praise, as well as matter for confession and petition. To this end, study the excellencies and goodness of the Lord, as frequently as thy own wants and unworthiness; the mercies thou hast received, and those which are promised, as often as the sins thou hast committed. _Praise is comely for the upright. Whoso offereth praise, glorifieth God. Praise ye the Lord, for the Lord is good; sing praises unto his name, for it is pleasant._[341] _Let us offer the sacrifice of praise to God continually, that is, the fruit of our lips, giving thanks to his name._[342] Had not David a most heavenly spirit, who was so much in this heavenly work? Doth it not sometimes raise our hearts, when we only read the Song of Moses, and the Psalms of David? How much more would it raise and refresh us, to be skilful and frequent in the work ourselves? O the madness of youth, that lay out their vigor of body and mind upon vain delights and fleshly lusts, which is so fit for the noblest work of man! And O the sinful folly of many of the saints, who drench their spirits in continual sadness, and waste their days in complaints and groans, and so make themselves, both in body and mind, unfit for this sweet and heavenly work! Instead of joining with the people of God in his praises, they are questioning their worthiness, and studying their miseries; and so rob God of his glory, and themselves of their consolation. But the greatest destroyer of our comfort in this duty, is our taking up with the tune and melody, and suffering the heart to be idle, which ought to perform the principal part of the work, and use the melody to revive and exhilarate itself.
