Mt. 3:7-10; ch.23; Jn 8:31-47; Rom. 2:6-11, 3:9; 10:12; Gal 3:28; 6:15; Col. 3:11, to cite but a few. Rom. 11:28 does not negate these, but should be interpreted in the context of Rom. 4 and 9:6-13. Trapper's rabid anti-semitism is one thing, but making national Israel central to God's plans for the future is almost certainly equally wrong.
