Romans 9:30-33

So what does all this mean? Those who are not Jews were not trying to make themselves right with God, but they were made right with God because of their faith. The people of Israel tried to follow a law to make themselves right with God. But they did not succeed, because they tried to make themselves right by the things they did instead of trusting in God to make them right. They stumbled over the stone that causes people to stumble. As it is written in the Scripture: “I will put in Jerusalem a stone that causes people to stumble, a rock that makes them fall. Anyone who trusts in him will never be disappointed.”
