So I ask, "Has God rejected his people Israel?" That's unthinkable! Consider this. I'm an Israelite myself, a descendant of Abraham from the tribe of Benjamin.
God has not rejected his people whom he knew long ago. Don't you know what Elijah says in the Scripture passage when he complains to God about Israel? He says,
"Lord, they've killed your prophets and torn down your altars. I'm the only one left, and they're trying to take my life."
But what was God's reply? God said, "I've kept 7,000 people for myself who have not knelt to worship Baal."
So, as there were then, there are now a few left that God has chosen by his kindness.
If they were chosen by God's kindness, they weren't chosen because of anything they did. Otherwise, God's kindness wouldn't be kindness.
