ROM 11:22

22 Note then, that God acts kindly, but he also acts severely. He has acted severely toward [the Jews] who have stopped trusting in him. On the other hand, he acts kindly toward each of you [non-Jews only] if you continue [to appreciate his acting] kindly [toward you]. However, you will be rejected {[he] will reject you} if you do not [keep trusting in him].
