'I cannot find in the whole book of God where he hath promised any such strength or power against this or that particular sin, as that the soul should be for ever, in this life, put out of a possibility of falling again and again into the same sins; and where God hath not a mouth to speak, I must not have a heart to believe. God will graciously pardon those sins to his people that he will not in this life effectually subdue in his people. I would go far to speak with that soul that can show me a promise, that when our sorrow and grief been so great, or so much, for this or that sin, that then God will preseve us from ever falling into the same sin. The sight of such a promise would be as life from the dead to many a precious soul, who desires nothing more than to keep close to Christ, and fears nothing more than backsliding from Christ.'
Thomas Brooks, Precious Remedies Against Satan's Devices, p.173.
