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.

The gospel shall be victorious. This is the third thing that greatly comforts and refreshes me, — that if God should give me the honour, the strength, and grace to die in this cause, my cause shall be victorious, as sure as if I had the crown in my hand.

Whatever vices and corruptions men see in the lives of their ministers will not be attributed to the depravity of their old nature which still abides in them, but to the gospel.

The least grace is a better security for heaven than the greatest gifts or privileges whatsoever.

The vigour, and power, and comfort of our spiritual life depends on the mortification of the deeds of the flesh...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...Do you mortify; do you make it your daily work; be always at it whilst you live; cease not a day from this work; be killing sin or it will be killing you.

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

Though we are commanded to 'wash ourselves', to 'cleanse ourselves from sins', to 'purge ourselves from all our iniquities', yet to imagine that we can do these things by our own efforts is to trample on the cross and grace of Jesus Christ. Whatever God works in us by his grace, he commands us to do as our duty. God works all in us and by us.
