The Law of Sinai and The Law in Zion
The difference between the law at Sinai and the law of God written on the heart of Christ's witness is this: the law at Sinai centers the doing on man, saying, "Do this and live"; the law of God written on the heart centers the doing on Christ saying, "Christ has finished it!" This is the message that makes Christ people willing to believe and testify of Him (Heb 10:9, 10; 14-18.)
