Is it wise to proclaim in so bald, naked, and unqualified a way as many do, that the holiness of converted people is by faith only, and not at all by personal exertion? Is it according to the proportion of God’s Word? I doubt it. That faith in Christ is the root of all holiness…no well-instructed Christian will ever think of denying. But surely the Scriptures teach us that in following holiness the true Christian needs personal exertion and work as well as faith.
