“For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law;”
King James Version (KJV)
2:12 For as many as have sinned - He speaks as of the time past, for all time will be past at the day of judgment. Without the law - Without having any written law. Shall also perish without the law - Without regard had to any outward law; being condemned by the law written in their hearts. The word also shows the agreement of the manner of sinning, with the manner of suffering. Perish - He could not so properly say, Shall be judged without the law.
Ro 2:12 For as many as have sinned without law. As many as shall be found in sin, at the judgment, without a special revelation of the law of God. While the Mosaic law is in the mind of the apostle, the statement is general. The principle is one of universal application. Those have sinned who have not lived up to their light. Shall also perish without law. They shall be judged and condemned without reference to the standards of revealed law. Law, in this verse, has no article in the Greek. When so used it means law in general. When, as occurs so often in Romans, it has the Greek definite article before it, the Mosaic law is meant. Observe that the Revised Version omits the article "the" in this verse. As many as have sinned in the law. Under a revelation of God's will. These shall be judged by the law, and condemned for disobedience to its commands.
