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.'

We admit no faith to be justifying, which is not itself and in its own nature a spiritually vital principle of obedience and good works.

Indwelling sin always abides whilst we are in this world; therefore it is always to be mortified.

If we would talk less and pray more about them, things would be better than they are in the world: at least, we should be better enabled to bear them.

The custom of sinning takes away the sense of it, the course of the world takes away the shame of it.

Christ by his death destroying the works of the devil, procuring the Spirit for us, hath so killed sin, as to its reign in believers, that it shall not obtain its end and dominion.

I will not judge a person to be spiritually dead whom I have judged formerly to have had spiritual life, though I see him at present in a swoon (faint)as to all evidences of the spiritual life. And the reason why I will not judge him so is this -- because if you judge a person dead, you neglect him, you leave him; but if you judge him in a swoon,(faint) though never so dangerous, you use all means for the retrieving of his life.
