(Rom 10:2) “For I bear them record that they have a zeal of God, but not according to knowledge. (3) For they being ignorant of God’s righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.” The righteousness of God is perfect. That is the standard to earn everlasting life. The law was to reveal this; this is why He gave them the law of sacrifice. Just as those with conscience towards God looked by faith to the sacrifice, the saved look by faith to the sacrifice of the Lord Jesus. This is where the nation of the Jews failed.
