Our assurance and rest is Christ alone

"And so again, when a poor soul feels a load of guilt; how is he to get rid of it? 'Oh!' say some people, 'begin to do your duty; and when you have done a little duty, then you are to take the comfort of the Bible.' I believe it is the devil's trap, to insult the Spirit of God and to deceive sinners. 'Why,' say you, 'you would not encourage them not to do their duty?' Nay, that is another thing. It becomes them to walk in the precepts of God and practice all what are called duties; but that will not do for a ground of comfort and happiness. If ever we feel guilt, and if God the Spirit does not apply the atonement and bring us to walk into the efficacy of the blood of God-man Mediator, and we get rid of guilt without it, it is the devil deceiving our souls and we have wrapped up ourselves in some sad delusion. Nothing but that can bring solid peace to the conscience and clear our sky of clouds." - William Gasdsby, Sermons, pg. 19
