He that hath slight thoughts of sin, never had great thoughts of God.

Christ's blood is the great sovereign remedy for sin-sick souls.

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.

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.

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.

Mortification from a self-strength, carried on by ways of self-invention, unto the end of a self-righteousness, is the soul and substance of all false religion in the world.

Without absolutes revealed from without by God Himself, we are left rudderless in a sea of conflicting ideas about manners, justice and right and wrong, issuing from a multitude of self-opinionated thinkers.
