Romans 10:17

And how will they preach unless they are sent? As it is written: "How beautiful are the feet of those who preach the Good News of peace, who bring glad tidings of good things!

But they didn't all listen to the glad news. For Isaiah says, "Lord, who has believed our report?

But I say, didn't they hear? Yes, most certainly, "Their sound went out into all the earth, their words to the ends of the world.

But I ask, didn't Israel know? First Moses says, "I will provoke you to jealousy with that which is no nation, with a nation void of understanding I will make you angry.
