Time and again in the history of the church, the truth that sinners are 'not justified by the works of the law but by faith in Jesus Christ' (Gal. 2:16) has been hidden from sight by those striving to find a place for mans's own righteousness alongside the righteousness of Christ's in justification. Fearing that free justification through the imputed righteousness of Christ opened the floodgate to lawlessness, such teachers have so qualified the biblical doctrine as to obscure the only way in which sinners may obtain 'peace with God, through our Lord Jesus Christ' (Rom. 5:1). Robert Traill (1642-1716), son of a Scottish Covenanting minister, fugitive, exile and prisoner on the Bass Rock during the 'Killing Times', wrote his masterly defence of the doctrine of justification by faith alone in 1692 to dispel such obscurity. With a brevity and clarity seldom equalled, 'Justification Vindicated' refutes false charges against and movingly affirms the biblical doctrine of justification by faith alone as the only door by which sinners may enter the presence of a holy God.
