Judaism: Works-based: Has following God ever been a "works-based" religion, as in the Old Testament when Jews were required to follow the Law or not go to heaven? [Hebrews 10:19-20, Hebrews 11, Genesis 15:6, Psalm 32:1, Galatians 5:6, James 2:26, Romans 4:8]. Old vs New Covenants: If both the Old Testament Jews and the New Testament believers were saved by faith, why then is there a "New Covenant?" What is new about it? [2 Corinthians 3].
