2. That the worship of God, according to his will, shall be more closely applied to, and more unanimously concurred in. Instead of sacrifice and incense, they shall call upon the name of the Lord. Prayer is the spiritual offering with which God must be honoured; and, to prepare and fit us for that duty, it is necessary that we have a pure language. We are utterly unfit to take God's name into our lips, unless they be pure lips. The purifying of the language in common conversation is necessary to the acceptableness of the words of our mouth and the meditation of our heart on our devotion; for how can sweet waters and bitter come out of the same fountain? James iii. 9-12. It is likewise promised that their language being thus purified they shall serve God with one consent, with one shoulder (so the word is), alluding to oxen in the yoke, that draw even. When Christians are unanimous in the service of God the work goes on cheerfully. This is the effect of the pure language, purified from passion, envy, and censoriousness. Note, Purity is the way to unity; the reformation of manners is the way to a comprehension. The wisdom from above is first pure, then peaceable.
