In Him we have redemption through His blood, the forgiveness of sins, according to the riches of His grace… – Ephesians 1:7

When the soul is seeking for Jesus, it is at the same time much grieved to find it cannot even now cease from sin...As if that poor heart expected to be perfect before it had even found pardon! As if a patient expected to be perfectly well before he had followed the advice of his physician! My dear hearer, if you were able to cease from all sin for a single day, I am sure you would be out of place on earth, for heaven is the place for perfect people, and not this sinful earth. If a fountain sent forth nothing but pure water for one whole day, we might conclude that it was completely purified. The bearing of good fruit for one season would prove the tree to be good. If your heart abstained from sin of itself throughout one day, it might for another, and so on forever, and where would be the need of a Savior? What, dost thou not know that Christ came to save thee from thy new sins as well as from thine old transgressions? Is His arm too short to reach thy daily needs? His blood of too little power to wash away thy fresh pollutions? Hast thou still some hope of bettering thyself? Have done with this trifling. Confess thyself a helpless sinner, shapen in iniquity, conceived in sin, depraved in heart, and, therefore, needing the never-ceasing mercy of the Lord thy God. Come, wash now in the fountain filled with blood, and if sin returneth, ask Jesus to wash thy feet again. Make Jesus your sole reliance. Cry to Him, “Purge me with hyssop, and I shall be clean; wash me, and I shall be whiter than snow.” Nothing else can end your perplexities; you cannot untie the Gordian knot of your difficulties, cut it, then, by leaving all to Jesus. You cannot overcome your sins except by the blood of the Lamb. You cannot be what you should be, nor what you would be, except by taking Jesus to be your all in all. ~ C.H. Spurgeon
