1. For proof of this, I must desire you to look back to all the arguments which proved the dueness of worship in general, for they will yet more especially prove this sort of worship, seeing prayer and praise are most immediately and eminently called God's worship of any; (under praises I comprehend psalms of praise, and under prayer, psalms of prayer;) yet let us add some more. _Arg._ I. It is God's will that christians who have fit occasions and opportunities for prayer and praises should improve them, but christian families have fit occasions and opportunities for prayer and praise, therefore it is God's will they should improve them. The major is evident in many Scripture precepts. 1 Tim. ii. 8, "I will therefore that men pray every where, lifting up holy hands, without wrath and doubting." 1 Thess. v. 17, 18, "Pray without ceasing; in every thing give thanks; for this is the will of God concerning you." Col. iv. 2, "Continue in prayer, and watch in the same with thanksgiving." Col. iii. 16, 17, "Teaching and admonishing one another in psalms, and hymns, and spiritual songs, singing with grace in your hearts unto the Lord: and whatsoever ye do in word or deed, do all in the name of the Lord Jesus; giving thanks unto God and the Father by him." Rom. xii. 12, "Continuing instant in prayer." "Praying always with all prayer and supplication in the spirit, and watching thereunto with all perseverance and supplication for all saints; and for me that utterance may be given me," Eph. vi. 18. Many the like texts might be named, every one of which afford an argument for family praises most effectual. 1. If men must pray every where, (that is convenient,) then sure in their families. But, &c. Erg. 2. If men must pray without ceasing, then sure in their families. 3. If men must in every thing give thanks, then sure in family mercies, and then, according to the nature of them, together. 4. If men must continue in prayer and watch in it, (for fit advantages and against impediments,) and in thanksgiving, then doubtless they must not omit the singular advantages which are administered in families. 5. If we must continue instant in prayer and supplication, &c. then doubtless in family prayer, in our families, unless that be no place and no prayer. _Object._ But this binds us no more to prayer in our families than any where else. _Answ._ Yes, it binds us to take all fit opportunities; and we have more fit opportunities in our own families than in other men's, or than in occasional meetings, or than in any ordinary societies, except the church.
