The Sufficiency of Grace Against Strange Doctrines – Hebrews 13:9

The Word signifies one that is tossed on the waves of the sea when they are agitated by the wind. And a similitude it is lively expressing both the nature of these strange doctrines, the way of spreading of them, and their effects on the minds of men. In themselves they are light and vain as the wind, or “clouds without water, carried about of winds.” And those who would impose them on others commonly do it with a great and vehement blustering. ‘You must be circumcised, or you cannot be saved!’ as Acts 15:1. ‘Unless you believe and practice these things, you are heretics, or schismatics, and cannot be saved!’ All imposition of doctrine is with such a noise and wind. And the effects of them on the minds of men are as those of contrary winds at sea. They toss men up and down; they turn them out of their course, and endanger their destruction. – John Owen
