John Wesley on Romans 11:32

For God hath shut up all together in disobedience - Suffering each in their turn to revolt from him. First, God suffered the gentiles in the early age to revolt, and took the family of Abraham as a peculiar seed to himself. Afterwards he permitted them to fall through unbelief, and took in the believing gentiles. And he did even this to provoke the Jews to jealousy, and so bring them also in the end to faith. This was truly a mystery in the divine conduct, which the apostle adores with such holy astonishment.
