Charles Spurgeon Commentary Romans 3:26-27

"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 3:26-27 (ASV)

To declare, I say, at this time his righteousness: that he might be just, and the justifier of him who believeth in Jesus. Where is boasting then?

Where is it? It is to be found in a great many people. It is common enough; but where ought it to be? Where does it get a footing? It is shut out! There is no room for boasting in the heart that receives Christ. If a man were saved by works, he would have reason to glory; boasting would not be shut out. But as salvation is all of grace, through faith in Christ, boasting is barred out in the dark, and faith gratefully ascribes all praise to God.
