For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. Romans 1:16

How then will they call on Him in whom they have not believed? How will they believe in Him whom they have not heard? And how will they hear without a preacher? And how will they preach unless they are sent? Just as it is written, "How beautiful are the feet of those who proclaim good news of good things!"  Romans 10:14-15
