Romans 10:1-4; Romans 10:13-15

1 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.

13 For "everyone who calls on the name of the Lord will be saved."

14 How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching?

15 And how are they to preach unless they are sent? As it is written, "How beautiful are the feet of those who preach the good news!"
