Faith is the Spring of Good Works
Convince them they cannot do these without grace from Christ; for want of which the heathen’s virtues were but gilded vices. We must come to good works by faith, and not to faith by good works. The tree must be good before the fruit can he so: ‘Without me ye can do nothing.’ Then convince them, when they are most exact in moral duties, this must not be their righteousness before God: the robe which must cover their souls must not be the homespun garment of their own inherent righteousness wrought in them, but of Christ’s righteousness which he wrought for them.
