Westminster Confession Of Faith – Lord’s Day 18
Chapter 11 – Of Justification (Paragraphs 1-3)
I. Those whom God effectually calls, he also freely justifies: not by infusing righteousness into them, but by pardoning their sins, and by accounting and accepting their persons as righteous; not for any thing wrought in them, or done by them, but for Christ’s sake alone; not by imputing faith itself, the act of believing, or any other evangelical obedience to them, as their righteousness; but by imputing the obedience and satisfaction of Christ unto them, they receiving and resting on him and his righteousness by faith; which faith they have not of themselves, it is the gift of God.
II. Faith, thus receiving and resting on Christ and his righteousness, is the alone instrument of justification; yet is it not alone in the person justified, but is ever accompanied with all other saving graces, and is no dead faith, but works by love.
III. Christ, by his obedience and death, did fully discharge the debt of all those that are thus justified, and did make a proper, real, and full satisfaction to his Father’s justice in their behalf. Yet inasmuch as he was given by the Father for them, and his obedience and satisfaction accepted in their stead, and both freely, not for any thing in them, their justification is only of free grace, that both the exact justice and rich grace of God might be glorified in the justification of sinners.
