The thing proceedeth from the Lord He, in his providence, evidently favoured it, and therefore they properly concluded that it was his will; which is the only safe rule of conduct in all cases. And in those which are of peculiar importance, as the proper choice of a partner in marriage certainly is, we should use every prudent means to know God's will, especially the means used by Abraham's servant, fervent prayer, and observing the openings of providence. A marriage is then likely to be comfortable, when it appears to proceed from the Lord.
