Faith thus receiving and resting on Christ and his righteousness, is the alone instrument of justification;⁶ yet is not alone in the person justified, but is ever accompanied with all other saving graces, and is no dead faith, but works by love.⁷

⁶ Rom. 3:28
⁷ Gal.5:6, James 2:17,22,26

Christ, by his obedience and death, did fully discharge the debt of all those who are justified; and did, by the sacrifice of himself in the blood of his cross, undergoing in their stead the penalty due to them, make a proper, real, and full satisfaction to God’s justice in their behalf;⁸ yet, in as much as he was given by the Father for them, and his obedience and satisfaction accepted in their stead, and both freely, not for anything in them,⁹ 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.¹⁰

⁸ Heb. 10:14; 1 Pet. 1:18–19; Isa. 53:5–6
⁹ Rom. 8:32; 2 Cor. 5:21
¹⁰ Rom. 3:26; Eph. 1:6–7, 2:7
