" If the cripple lay not the whole weight of his body upon a strong staff, but part of it upon a rotten one, he is like to receive a fall. If the swimmer will not commit his body wholly to the water to bear him up, but catch at weeds, or struggle to feel out ground, he may sink to the bottom. Christ will be all our salvation, or nothing. If we seek to be saved any other way, as the Galatians did by circumcision, Christ will profit us nothing (Gal. 5:2). "
