Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.
Ver. 1. Having therefore, &c.] Faith in the promises purifieth the heart, Acts 15:9, and argueth notably from mercy to duty, melting the hardness of it by the consideration of the promises. Let a cart loaded go over a frozen river, the cart breaks the ice, but it remains ice still. But let the sun shine upon the river, and it dissolveth it. The apostle saith not, Having these menaces, but, Having these promises.
From all filthiness] Sin defileth a man worse than any jakes or leprosy. It is the devil's excrement, it is the corruption of a dead soul. Seldom or never is there a birth of saving grace, but there follows it a flux of mortification.
Of flesh and spirit] i.e. Both of the outward and inward man. Or of flesh, that is, worldly lusts, and gross evils, as uncleanness, earthlymindedness, &c, And of spirit, that is, more spiritual lusts, as pride, presumption, self-flattery, &c. These lie more up in the heart of the country, as it were; those others in the frontiers and skirts of it.
Perfecting holiness] Propounding to ourselves the highest pitch and the best patterns. And having for our motto that of Charles V, Plus ultra, further yet. And here let faith and obedience make a perfect pair of compasses. Faith as the one foot must be pitched upon the centre, God, while obedience (as the other) walks about in a perfect circle of all good duties. He will not crush but cherish that worm Jacob. "He will not break the bruised reed," &c.
In the fear of God] Which is the fountain whence holiness flows. See Proverbs 8:13 .
