Romans 10:1 Brothers and sisters, my heart’s desire and prayer to God on behalf of my fellow Israelites is for their salvation. 10:2 For I can testify that they are zealous for God, but their zeal is not in line with the truth. 10:3 For ignoring the righteousness that comes from God and seeking instead to establish their own righteousness, they did not submit to God’s righteousness. 10:4 For Christ is the end of the law, with the result that there is righteousness for everyone who believes.

If we ignore that our righteousness is from God, we will try to establish our own righteousness. Jesus is the righteousness for everyone who believes and receives His righteousness.
