The Main Issue - Faith in Jesus Christ!

Romans 9:33-10:4
“Behold, I am laying in Zion a stone of stumbling, and a rock of offense;
    and whoever believes in him will not be put to shame.”
Brothers, my heart's desire and prayer to God for them is that they may be saved. For I bear them witness that they have a zeal for God, but not according to knowledge. For, being ignorant of the righteousness of God, and seeking to establish their own, they did not submit to God's righteousness. For Christ is the end of the law for righteousness to everyone who believes.
