Hence I may fetch many arguments for family prayers. 1. It appeareth to be family prayers principally that the apostle here speaketh of; for it is families that he speaks to: for in ver. 16, 17, he speaketh of prayer and thanksgiving; and in the next words he speaketh to each family relation, wives, husbands, children, parents, servants, masters; and in the next words, continuing his speech to the same persons, he bids them "continue in prayer, and watch in the same," &c. If neighbours are bound to speak together in psalms, and hymns, and spiritual songs, with grace in their hearts to the Lord, and to continue in prayer and thanksgiving; then families much more, who are nearlier related, and have more necessities and opportunities, as is said before. 3. If whatever we do in word or deed, we must do all in the name of the Lord Jesus, giving thanks; then families must needs join in giving thanks. For they have much daily business in word and deed to be done together and asunder. _Arg._ XV. From Dan. vi. 10, "When Daniel knew that the writing was signed, he went into his house, and his window being open in his chamber towards Jerusalem, he kneeled upon his knees three times a day, and prayed, and gave thanks before his God, as he did aforetime. Then these men assembled, and found Daniel praying and making supplication before his God." Here note, 1. The nature of the duty. 2. The necessity of it. 1. If it had not been open, family prayer which Daniel here performed, how could they have known what he said? It is not probable that he would speak so loud in secret; nor is it like they would have found him at it. So great a prince would have had some servants in his outward rooms, to have stayed them before they had come so near. 2. And the necessity of this prayer is such, that Daniel would not omit it for a few days to save his life. _Arg._ XVI. From Josh. xxiv. 15, "But as for me and my house, we will serve the Lord." Here note, 1. That it is a household that is here engaged: for if any would prove that it extendeth further, to all Joshua's tribe, or inferior kindred, yet his household would be most eminently included. 2. That it is the same thing which Joshua promiseth for his house, which he would have all Israel do for theirs: for he maketh himself an example to move them to it. If households must serve the Lord, then households must pray to him and praise him: but households must serve him; therefore, &c. The consequence is proved, in that prayer and praise are so necessary parts of God's service, that no family or person can be said in general to be devoted to serve God, that are not devoted to them. Calling upon God is oft put in Scripture for all God's worship, as being a most eminent part; and atheists are described to be such as "call not upon the Lord," Psal. xiv. &c.
