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

When sin lets us alone we may let sin alone; but as sin is never less quiet than when it seems to be most quiet, and its waters are for the most part deep when they are still, so ought our contrivances against it to be vigorous at all times and in all conditions, even where there is least suspicion.

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.

When the heart is once won to rest in God, to repose himself on him, he will assuredly satisfy it. He will never be as water that fails; nor hath he said at any time to the seed of Jacob, "Seek ye my face in vain." If Christ be chosen for the foundation of our supply, he will not fail us.

All spiritual acts well-pleasing unto God, as faith, repentance, obedience, are supernatural; flesh and blood revealeth not these things.

It is the Spirit alone that can mortify sin; he is promised to do it, and all other means without him are empty and vain. How shall he, then, mortify sin that has not the Spirit? A man may easier see without eyes, speak without a tongue, than truly mortify one sin without the Spirit.

A river continually fed by a living fountain may as soon end its streams before it come to the ocean, as a stop be put to the course and progress of grace before it issue in glory.
