Romans 11:2-6

God has not rejected His [chosen] people whom He foreknew. Or do you not know what the Scripture says of Elijah, how he pleads with God against Israel? [Ps 94:14; 1 Kin 19] “Lord, THEY HAVE KILLED YOUR PROPHETS, THEY HAVE TORN DOWN YOUR ALTARS, AND I ALONE AM LEFT [of the prophets], AND THEY ARE SEEKING MY LIFE.” But what is God’s response to him? “I HAVE KEPT for Myself SEVEN THOUSAND MEN WHO HAVE NOT BOWED THE KNEE TO BAAL.” [1 Kin 19:18] So too then, at the present time there has come to be a remnant [a small believing minority] according to God’s gracious choice. But if it is by grace [God’s unmerited favor], it is no longer on the basis of works, otherwise grace is no longer grace [it would not be a gift but a reward for works].
