Romans 10:14-15New King James Version (NKJV)
14 How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher? 15 And how shall they preach unless they are sent? As it is written: “How beautiful are the feet of those who preach the gospel of peace,
Who bring glad tidings of good things!
