31:9-15 All the defilements of the life come from a deceived heart. Lust is a fire in the soul: those that indulge it, are said to burn. It consumes all that is good there, and lays the conscience waste. It kindles the fire of God's wrath, which, if not quenched by the blood of Christ, will consume even to eternal destruction. It consumes the body; it consumes the substance. Burning lusts bring burning judgments. Job had a numerous household, and he managed it well. He considered that he had a Master in heaven; and as we are undone if God should be severe with us, we ought to be mild and gentle towards all with whom we have to do.
