_Arg._ V. It is a duty to receive all the mercies that God offereth us: but for a family to have access to God in joint prayers and praises, is a mercy that God offereth them; therefore it is their duty to accept it. The major is clear in nature and Scripture, Because I have offered and ye refused, is God's great aggravation of the sin of the rebellious. "How oft would I have gathered you together, and ye would not! All the day long have I stretched out my hand," &c. To refuse an offered kindness, is contempt and ingratitude. The minor is undeniable by any christian, that ever knew what family prayers and praises were. Who dare say that it is no mercy to have such a joint access to God? Who feels not conjunction somewhat help his own affections, who makes conscience of watching his heart? _Arg._ VI. Part of the duties of families are such that they apparently lose their chiefest life and excellency if they be not performed jointly; therefore they are so to be performed. I mean, singing of psalms, which I before proved an ordinary duty of conjunct christians, therefore of families. The melody and harmony are lost by our separation, and consequently the alacrity and quickening which our affections should get by it. And if part of God's praises must be performed together, it is easy to see that the rest must be so too. (Not to speak of teaching, which cannot be done alone.) _Arg._ VII. Family prayer and praises are a duty owned by the teaching and sanctifying work of the Spirit; therefore they are of God. I would not argue backwards from the Spirit's teaching to the word's commanding, but on these two suppositions; 1. That the experiment is very general, and undeniable. 2. That many texts of Scripture are brought already for family prayer; and that this argument is but to second them and prove them truly interpreted. The Spirit and the word do always agree: if therefore I can prove that the Spirit of God doth commonly work men's hearts to a love and savour of these duties, doubtless they are of God. Sanctification is a transcript of the precepts of the word on the heart, written out by the Spirit of God. So much for the consequence.
