“Great multitudes of ignorant people that live under the gospel harden their hearts in sin, and ruin their souls for ever, by trusting on Christ for such an imaginary salvation as does not consist at all in holiness, but only in forgiveness of sin and deliverance from everlasting torments. They would be free from the punishment due to sin, but they love their lusts so well that they hate holiness, and would not be saved from the service of sin. The way to oppose this pernicious delusion is not to deny, as some do, that trusting on Christ for salvation is a saving act of faith, but rather to show that none do or can trust on Christ for true salvation, except they trust on Him for holiness; neither do they heartily desire true salvation, if they do not desire to be made holy and righteous in their hearts and lives. If ever God and Christ give you salvation, holiness will be one part of it; if Christ does not wash you from the filth of your sins, you have no part with Him (John 13:8). What a strange kind of salvation do they desire, that do not care for holiness? They would be saved, and yet be altogether dead in sin, aliens from the life of God, bereft of the image of God, deformed by the image of Satan, his slaves and vassals to their own filthy lusts, utterly unsuitable for the enjoyment of God in glory. Such a salvation as that was never purchased by the blood of Christ, and those that seek it abuse the grace of God in Christ and turn it into lasciviousness.”
