Romans 10:1-4:

Brothers, my heart's desire and prayer to God for them is that they may be saved. 2 For I bear them witness that they have a zeal for God, but not according to knowledge. 3 For, being ignorant of the righteousness of God, and seeking to establish their own, they did not submit to God's righteousness. 4 For Christ is the end of the law for righteousness to everyone who believes.
