Romans 3:26

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

to demonstrate his righteousness at this present time; that he might himself be just, and the justifier of him who has faith in Jesus.

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.

for the shewing forth of His righteousness in the present time, for His being righteous, and declaring him righteous who `is' of the faith of Jesus.

He did this to demonstrate His righteousness at the present time, so as to be just and to justify the one who has faith in Jesus.
