So speak ye, and so do, as they that shall be judged by the law of liberty. For he shall have judgment without mercy, that hath shewed no mercy; and mercy rejoiceth against judgment. ~ James 2:12-13 KJV

Speak and act as those who are going to be judged by the law that gives freedom, because judgement without mercy will be shown to anyone who has not been merciful. Mercy triumphs over judgement. ~ James 2:12-13 NIV (1984)

So speak and so act as [people should] who are to be judged under the law of liberty [the moral instruction given by Christ, especially about love]. For to him who has shown no mercy the judgment [will be] merciless, but mercy [full of glad confidence] exults victoriously over judgment. ~ James 2:12-13 AMP
