Matthew Poole and continuators on Romans 3:26

26. To declare I say at this time his righteousness : that he might be just, and the justifier of him which believeth in Jesus .

He repeats the final Cause of Justification, viz. The making the aforesaid Declaration of the Righteousness of God, in the time of the Gospel, and Dispensation, and Ministry thereof, 2 Cor. 6.2. which is taken out of Isa. 49.8.

i. e. That no Wrong might be done to the Essential Purity of his Nature, or Rectitude of his Will; nor yet to his immediate Justice, by which he cannot but hate Sin, and abhor the Sinner as such; though in the mean time he gives a Discharge to him, that is of the Faith of Iesus (as 'tis in the Original) Or of the Number of those that Believe, and Cast themselves upon a Saviour.
