“You are more sinful than you can imagine! The doctrine of Original Sin is true! You cannot reform your flesh! You cannot become a better person by your own strength no matter how hard you try! But cheer up! If you are a Christian, you have come into union with Christ. Through faith in Jesus Christ you are forgiven. Through faith in Jesus Christ you are sanctified and made holy. Through Christ, you are a new creation! The Holy Spirit lives in you! Therefore, pursue the life of faith in Christ with all diligence.”

Walter Marshall, The Gospel Mystery of Sanctification (updated edition), p. 13
