Spiritual wisdom consists in finding out the subtleties, policies, and depths of any indwelling sin... to trace this serpent in all its turnings and windings; be able to say, at its most secret actings, 'This is your old way and course; I know what you aim at.'

I have known some good men who have been so addicted to their study, that they have thought the last day of the week sufficient to prepare for their ministry, though they employ all the rest of the week in other studies. But your business is to trade with your spiritual abilities. ... A man may preach a very good sermon, who is otherwise himself; but he will never make a good minister of Jesus Christ, whose mind and heart are not always in the work. Spiritual gifts will require continual ruminating on the things of the Gospel in our minds.

All that may be known of God for our salvation, especially his wisdom, love, goodness, grace and mercy on which the life of our souls depends, are represented to us in all their splendour in and through Christ. No wonder then that Christ is glorious in the eyes of believers!

As among all the doctrines of the gospel, there is none opposed with more violence and subtlety than that concerning our regeneration by the immediate, powerful, effectual operation of the Holy Spirit of grace.

Unless we are thoroughly convinced that without Christ we are under the eternal curse of God, as the worst of His enemies, we shall never flee to Him for refuge.

If Scripture has more than one meaning, it has no meaning at all.

The choicest believers, who are assuredly freed from the condemning power of sin, ought yet to make it their business all their days to mortify the indwelling power of sin.
