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.

The foundation of true holiness and true Christian worship is the doctrine of the gospel, what we are to believe. So when Christian doctrine is neglected, forsaken, or corrupted, true holiness and worship will also be neglected, forsaken, and corrupted.

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

Let, then, the word be preached, and the sins of men will be rebuked, lust will be restrained, and some oppositions will be made against sin, though that be not the effect aimed at.

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.

There is not a day but sin foils or is foiled, prevails or is prevailed upon. It will always be so while we live in this world. Sin will not spare for one day. There is no safety but in a constant warfare for those who desire deliverance from sin's perplexing rebellion.
