At this point remains the fourth practice, concerning care for the knowledge of God (Hos. 6:3). And this care, if first you consider persons, applies to the following: (1) magistrates, that they may not be content to have provided a knowledge of God for themselves, but that they may in every way take care, by their example, by their calling of qualified teachers, and even as circumstances arise, by their own instruction, to confer and augment the knowledge of God in their subjects, according to the example of Moses, Joshua, David, Solomon, and others. (2) Ministers, upon whom it is preeminently incumbent by their office to instill in their hearers the knowledge of God, and namely that knowledge which is the basis of all faith, religion, and godliness, according to the judgment of the text, that God exists (John 14:8; 2 Peter 1:1–2; Phil. 1:9). (3) Every believer (see the same passages).
