In the King James Version, 1 John 3:4 defines sin as “the transgression of the law.” John was referring to the law of God, but how do we define the law of God for Christians today? We know it can’t be all of the laws of the Old Testament, because the New Testament shows that the sacrificial system has ended.
But what about other Old Testament laws? Are they as binding on Christians today as they were for Israelites before the coming of Jesus Christ? Which Old Testament laws does God command Christians to obey today?
