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.'

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.

And as men diversions increase from the world, so do their entanglements from Satan. When they have more to do in the world than they can well manage, they shall have more to do from Satan than they can withstand.

Only what God has commanded in His word should be regarded as binding; in all else there may be liberty of actions.

Christ is the meat, the bread, the food of our souls. Nothing is in him of a higher spiritual nourishment than his love, which we should always desire.

All other ways of mortification are vain, all helps leave us helpless; it must be done by the Spirit.

Sin aims always at the utmost; every time it rises up to tempt or entice, if it has its own way it will go out to the utmost sin in that kind. Every unclean thought or glance would be adultery if it could, every thought of unbelief would be atheism if allowed to develop. Every rise of lust, if it has its way reaches the height of villainy; it is like the grave that is never satisfied. The deceitfulness of sin is seen in that it is modest in its first proposals but when it prevails it hardens men’s hearts, and brings them to ruin.
