Adventist Teaching: To reveal your sin, the holiness of God, and the standard by which one must measure up to in order to be found worthy of the atoning benefits of Christ’s sacrifice. It is the standard by which all people will have their thoughts, words, deeds and motives judged in the Investigative Judgment. It is obedience to the Law, through faith, that reconciles you to God. Jesus came to exalt the Law before all nations, tongues and peoples. It’s requirement for man is the same as it was for Adam in Eden—perfect obedience to it.
Biblical Teaching: To reveal your sin (Romans 3:20-22), the holiness and perfect standard that God requires (Romans 7:12), and the standard by which one is condemned and how far you fall short of the holiness of God. This Law hung over the heads of all of humanity through the sinful act of Adam in the Garden of Eden (Romans 5:12-14) condemning all of the human race. But Jesus Christ, the Second Adam (1 Corinthians 15:45-49, Romans 5:12-17) did what the first Adam failed to do, fulfilling all righteousness (Matthew 3:14), obeying perfectly to the point of death (Philippians 2:8) and freed His people from being under the condemnation of the Law (Galatians 4:4-7, Romans 8:1), thus abrogating it as a covenant (Hebrews 8:13). We are saved by Christ’s perfect obedience to the Law and he gives us his perfect righteousness which is completely sufficient and cannot be added to (Philippians 3:9-10; 2 Corinthians 5:21).
The SDA Church’s fundamental issue is their rejection of the law gospel distinction which is a foundational aspect to grasp to rightly handle the Bible.
The Law (Covenant of Works) does not reconcile, it condemns and brings death (Romans 8:3, 2 Corinthians 3:6). It justifies no flesh (Romans 3:20-22). The Gospel (Covenant of Grace) is what brings peace, reconciliation, forgiveness of sins, etc. This is a distinct covenant from the Law that Believers are under and, in that covenant, are seen as holy and righteous “in Christ” through their faith (Romans 4:1-3) and already have peace with God (Romans 5:1) such that nothing can condemn them, even the Law (Romans 8:1), because the Law would have to be able to condemn Christ to condemn them.
