Section 941
II. To enquire into the author, or efficient cause of justification, who is the great God of heaven and earth
It is God that justifies; (Romans 8:34) which may well be wondered at, when it is considered that he is the supreme Judge of all, who will do right; that his law is the rule by which he acts in this affair; that this law is broken by the sin of man; that sin, which is a breach of the law, is especially committed against him, and is hateful to him; that he is a God that will not admit of an imperfect righteousness, in the room of a perfect one; and that he has power to condemn, and reason sufficient to do it; when, I say, these things are considered, it is amazing that this God should justify. For the farther illustration of this head, I shall endeavour to shew the concern that all the three Persons, Father, Son, and Spirit, have in the justification of the elect.
1. God the Father is the contriver of the scheme and method of our justification; he was in Christ, reconciling the world to himself, not imputing their trespasses; (2 Corinthians 5:19) he drew the model and platform of it, which is Nodus Deo vindice dignus. It would have remained a puzzling question to men and angels, how should man be just with God? had not his grace employed his wisdom to find out a ransom, whereby he has delivered his people from going down to the pit of corruption; which ransom is no other than his own Son, whom he sent, in the fulness of time, to execute the scheme he had so wisely formed in his eternal mind which he did by finishing transgression, making an end of sin, making reconciliation for iniquity, and bringing in an everlasting righteousness; which righteousness, being wrought out by Christ, God was well pleased with, because hereby his law was magnified and made honourable; and, having graciously accepted of it, he imputes it freely to all his people, and reckons their righteous on the account of it.
2. God the Son, as God, is the co-efficient cause of it, with his Father. As he has equal power with him to forgive sin, he also has to acquit, discharge, and justify from it. As Mediator, he is the Head and Representative; in whom all the seed of Israel are justified; as such, he has wrought out a righteousness, answerable to the demands of the law, by which they are justified; and is the Author and Finisher of that faith, which looks unto, lays hold on, and apprehends that righteousness for justification.
3. God the Holy Ghost convinces men of the weakness, imperfection, and insufficiency of their own righteousness to justify them before God; he brings near, and sets before them, the righteousness of Christ, and works faith in them to lay hold on it, and receive it; he intimates to their consciences the justifying sentence of God, on the account of Christ's righteousness, and bears a testimony to and with their spirits, that they are justified persons; and hence the saints are said to be justified in the name of the Lord Jesus, and by the Spirit of our God; (1 Corinthians 6:11) but this testimony of the Spirit is not so properly justification in itself, as an actual perception of it, before granted, by a kind of a reflex act of faith, as Dr. Ames expresses it. Now this is the part which Father, Son, and Spirit, severally bear in justification: the Father has contrived it, the Son has procured it, and the Spirit applies it. I go on,
