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.

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.

Sin will be always acting, if we be not always mortifying, we are lost creatures.

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.

There wanted not some beams of light to guide men in the exercise of their Stocastick faculty.

Consider that it is not failing in this or that attempt to come to Christ, but a giving-over of your endeavors, that will be your ruin.

The more I see of the glory of Christ, the more the painted beauties of this world will wither in my eyes.
