Charles Spurgeon Commentary Romans 3:25-27

"whom God set forth [to be] a propitiation, through faith, in his blood, to show his righteousness because of the passing over of the sins done aforetime, in the forbearance of God; for the showing, [I say], of his righteousness at this present season: that he might himself be just, and the justifier of him that hath faith in Jesus. Where then is the glorying? It is excluded. By what manner of law? of works? Nay: but by a law of faith." — Romans 3:25-27 (ASV)

Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; to declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus. Where is boasting then?

Boasting is sure to be somewhere handy, ready to creep in if it can, for we are all prone to it; it is the common sin of our race: Where is boasting then?

Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; to declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus. Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith.

Faith's empty hand receives the free gift of grace, and that very fact excludes all boasting.
