Excerpt from Summary of Christian Doctrine by Louis Berkhof

1. The Nature and Elements of Justification. Justification may be defined as that legal act of God by which He declares the sinner righteous on the basis of the perfect righteousness of Jesus Christ. It is not an act or process of renewal, such as regeneration, conversion, or sanctification, and does not affect the condition but the-state of the sinner. It differs from sanctification in several particulars. Justification takes place outside of the sinner in the tribunal of God, removes the guilt of sin, and is an act which is complete at once and for all time; while sanctification takes place in man, removes the pollution of sin, and is a continuous and lifelong process. We distinguish two elements in justification, namely: (a) The forgiveness of sins on the basis of the righteousness of Jesus Christ. The pardon granted applies to all sins, past, present, and future, and therefore does not admit of repetition, Ps. 103: 12; Isa. 44:22; Rom. 5:21; 8:1, 32-34; Heb. 10:14. This does not mean that we need no more pray for forgiveness, for the consciousness of guilt remains, creates a feeling of separation, and makes it necessary to seek repeatedly the comforting assurance of forgiveness, Ps. 25:7; 32:5; 51:1; Matt. 6:12; Jas. 5:15; I John 1:9. (b) The adoption as children of God. In justification God adopts believers as His children, that is, places them in the position of children and gives them all the rights of children, including the right to an eternal inheritance, Rom. 8:17; I Pet. 1:4. This legal sonship of believers should be distinguished from their moral sonship through regeneration and sanctification. Both are indicated in the following passages: John 1:12, 13; Rom. 8:15, 16; Gal. 4:5, 6.

2. The Time of Justification. The word ‘justification’ is not always used in the same sense. Some even speak of a fourfold justification: a justification from eternity, a justification in the resurrection of Christ, a justification by faith, and a public justification in the final judgment. In explanation of this it may be said that in an ideal sense the righteousness of Christ is already accounted to believers in the counsel of redemption, and therefore from eternity, but this is not what the Bible means when it speaks of the justification of the sinner. We must distinguish between what was decreed in the eternal counsel of God and what is realized in the course of history. Again, there is some reason for speaking of a justification in the resurrection of Christ. In a sense it may be said that the resurrection was the justification of Christ, and that in Him the whole body of believers was justified. But this was a general and purely objective transaction, which should not be confused with the personal justification of the sinner. When the Bible speaks of the justification of the sinner, it usually refers to the subjective and personal application and appropriation of the justifying grace of God. The usual representation is that we are justified by faith. This implies that it takes place at the time when we accept Christ by faith. Faith is called the instrument or the appropriating organ of justification. By faith man appropriates, that is, takes unto himself, the righteousness of Christ, on the basis of which he is justified before God. Faith justifies in so far as it takes possession of Christ. Rom. 4:5; Gal. 2:16. We should guard against the error of the Roman Catholics and the Arminians, that man is justified on the basis of his own inherent righteousness, or of his faith. Man’s own righteousness or faith can never be the ground of his justification. This can be found only in the perfect righteousness of Jesus Christ, Rom. 3:24; 10:4; II Cor. 5:21; Phil. 3:9.

3. Objections to the Doctrine of Justification. Various objections are raised to this doctrine. It is said that, if man is justified on the basis of the merits of Christ, he is not saved by grace. But justification, with all that it includes, is a gracious work of God. The gift of Christ, God’s reckoning of His righteousness to us, and His dealing with sinners as righteous,– it is all grace from start to finish. Again, it is said to be unworthy of God to declare sinners righteous. But God does not declare that they are righteous in themselves, but that they are clothed with the righteousness of Jesus Christ. And, finally, it is said that this doctrine is apt to make people indifferent as to their moral life. If they are justified apart from any consideration of works, why should they care for personal piety? But justification lays the foundation for a living relationship with Christ, and this is the surest guarantee for a truly godly life. The man who is really in living union with Christ cannot be morally indifferent. Rom. 3:5-8.
