He that is the master of a family, he has, as under that relation, a work to do for God; the right governing of his own family. And his work is twofold. First, Touching the spiritual state of it. Second, Touching the outward state of it. (Josh 24:15)
First, As touching the spiritual state of his family; he should be very diligent and circumspect, doing his utmost endeavor both to increase faith where it is begun, and to begin it where it is not. For this reason, he should diligently and frequently lay before his household such things of God, out of his word, as are suitable for each particular (Phil 4:8).
Second, touching the outward state; If you are father, then you are to consider your calling under this relation. Your children have souls, and they must be born of God as well as of you, or they perish. And know also, that unless you be very circumspect in your behavior to and before them, they may perish through you: the thoughts of which should provoke you, both to instruct, and also to correct them (Eph 6:4; Deu 6:7). If you are a husband, in a word, be such a husband to your believing wife, that she may say, God has not only given me a husband, but such a husband as preaches to me everyday the behavior of Christ to his church (Eph 5:8, 29). by John Bunyan
