Although I am a sinner, yet I despair not: for Christ, who is my Redeemer and my righteousness, lives. In Him I have no sin, no fear, no sting of conscience, and no fear of judgment: for in Him there is no condemnation. I am indeed a sinner as touching this present life; but I have a righteousness of God which is above this life, who is Christ my Lord. In Him I rejoice!
— Martin Luther
God's device for the sanctification of an unholy world is that sinners unite with Christ and derive holiness from him, whom the Father has constituted the head of sanctifying influences.
Union with Christ is the only way to sanctification. Thomas BostonYou say: “I can’t forgive myself.”
Christ says: “I have forgiven you.” You say: “I am unworthy of Your love.” Christ says: “I have loved you with an everlasting love.” You say: “I deserve punishment.” Christ says: “I took your punishment upon Myself.” You say: “I am haunted by my past sins.” Christ says: “I remember your sins no more.” You say: “I have sinned too much.” Christ says: “Where sin abounded, my grace did much more abound.” You say: “I have hidden sins.” Christ says: “I am faithful and just to forgive.” You say: “I am guilty.” Christ says: “I bore your guilt.” You say: “I feel condemned.” Christ says: “There is now no condemnation to those who are in Me.” You say: “I have failed again.” Christ says: “My mercies are new every morning.” You say: “I am burdened by sin.” Christ says: “Your sins are forgiven.” You say: “I am beyond redemption.” Christ says: “I am mighty to save.” You say: “I have run away from You.” Christ says: “I left the ninety-nine to find you.” You say: “l am a great sinner” Christ says: "I will in no wise cast you out.” No obstacle, no challenge, no objection can hinder the Savior. His plans are steadfast, His promises sure. Trust in Him.
