When we realize a constant enemy of the soul abides within us, what diligence and watchfulness we should have! How woeful is the sloth and negligence then of so many who live blind and asleep to this reality of sin. There is an exceeding efficacy nad power in the indwelling sin of believers, for it constantly inclines itself towards evil. We need to be awake, then, if our hearts would know the ways of God. Our enemy is not only upon us, as it was with Samson, but it is also in us.

There is a state of perfect peace with God to be attained under imperfect obedience.

Mortification from a self-strength, carried on by ways of self-invention, unto the end of a self-righteousness, is the soul and substance of all false religion in the world.

Because he is; that is, because he is an infinitely glorious, good, wise, holy, powerful, righteous, self-subsisting , self-sufficient , and all-sufficient being; the fountain and author of all being and good; the first cause, last end, and sovereign Lord of all; therefore, he is to be worshipped: therefore, are we to admire, adore, and love him; to praise, to trust and to fear him.

A natural man hath no such thing as free-will at all, if you take it for a power of doing that which is good and well-pleasing unto God in things spiritual.

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

It being our duty to mortify... we must be at work. He that is appointed to kill an enemy, if he leave striking before the other ceases living, does but half his work.
