To declare, I say, at this time, his righteousness
This end is further explained, it being to declare the righteousness of God "at this time", under the Gospel dispensation; in which there was such a display of the grace, mercy, and goodness of God:
that he might be just;
that is, appear to be so: God is naturally and essentially just in himself; and he is evidentially so in all his works, particularly in redemption by Christ; and when and while he is
the justifier of him that believeth in Jesus:
Jesus, the Saviour, is the object of faith, as he is the Lord our righteousness; the believer in Jesus is a real, and not a nominal one; God is the justifier of such in a declarative way, and God only, though not to the exclusion of the Son and Spirit; and which sentence of justification is pronounced by him on the foot of a perfect righteousness, which neither law nor justice can find fault with, but entirely approve of; and so he appears just and righteous, even though he justifies the sinner and the ungodly.
