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.'

That wisdom which cannot teach me that God is love, shall ever pass for folly.

It is evident that you contend against sin merely because of how it troubles you.

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.

No heart can conceive that treasury of mercies which lies in this one privilege, in having liberty and ability to approach unto God at all times, according to his mind and will.

Let no man pretend to fear sin that does not fear temptation also! These two are too closely united to be separated. He does not truly hate the fruit who delights in the root.

The greatest sorrow and burden you can lay on the Father, the greatest unkindness you can do to him is not to believe that he loves you.
