The first and principal duty of a pastor is to feed the flock by diligent preaching of the word

Your state is not at all to be measured by the opposition that sin makes to you, but by the opposition you make to it.

Let no man think to kill sin with few, easy, or gentle strokes. He who hath once smitten a serpent, if he follow not on his blow until it be slain, may repent that ever he began the quarrel. And so he who undertakes to deal with sin, and pursues it not constantly to the death.

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.

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

Then are we servants of God, then are we the disciples of Christ, when we do what is commanded us and because it is commanded us.

As a tender and loving friend is grieved at the unkindness of his friend... so is it with this tender and loving Spirit, who hath chosen our hearts for a habitation to dwell in.
