But of Him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption… – 1 Corinthians 1:30

When a man comes in very deed to a knowledge of the truth about faith in Christ, he trusts Christ, and he is there and then saved from the guilt of sin; and he begins to be saved altogether from sin. God cuts the root of the power of sin that very day; but yet it has such life within itself that at the scent of water it will bud again. Sin in our members struggles to live. It has as many lives as a cat: there is no killing it. Now, when we come to a knowledge of the truth, we begin to learn how sin is to be killed in us-how the same Christ that justifies, sanctifies, and works in us according to His working who worketh in us mightily, that we may he conformed to the image of Christ, and made meet to dwell with perfect saints above. Beloved, many of you that are saved from the guilt of sin, have a very hard struggle with the power of sin, and have much more conflict, perhaps, than you need to have, because you have not come to a knowledge of all the truth about indwelling sin. I therefore beg you to study much the Word of God upon that point, and especially to see the adaptation of Christ to rule over your nature, and to conquer all your corrupt desires, and learn how by faith to bring each sin before Him that, like Agag, it may be hewed in pieces before His eyes. You will never overcome sin except by the blood of the Lamb. There is no sanctification except by faith. The same instrument which destroys sin as to its guilt must slay sin as to its power. “They overcame by the blood of the Lamb,” and so must you. Learn this truth well, so shall you find salvation wrought in you from day to day.~ C.H. Spurgeon
