Yeah, the Jews believed in God, and were zealous, but were ignorant of God's righteousness...going about to establish their own. Exactly what you do.
Romans 10:1-4
Brethren, my heart's desire and prayer to God for Israel is, that they might be saved. For I bear them record that they have a zeal of God, but not according to knowledge. 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. For Christ is the end of the law for righteousness to every one that believeth.
God's righteousness can ONLY come through the Lord of Righteousness to every one that believes. YOU have not yet submitted to the righteousness of God nor do you believe what our Lord accomplished on the cross.
