Romans 10:10-15

For with the heart a person believes [in Christ as Savior] resulting in his justification [that is, being made righteous—being freed of the guilt of sin and made acceptable to God]; and with the mouth he acknowledges and confesses [his faith openly], resulting in and confirming [his] salvation. For the Scripture says, “WHOEVER BELIEVES IN HIM [whoever adheres to, trusts in, and relies on Him] WILL NOT BE DISAPPOINTED [in his expectations].” [Is 28:16] For there is no distinction between Jew and Gentile; for the same Lord is Lord over all [of us], and [He is] abounding in riches (blessings) for all who call on Him [in faith and prayer]. For “WHOEVER CALLS ON THE NAME OF THE LORD [in prayer] WILL BE SAVED.” [Joel 2:32] But how will people call on Him in whom they have not believed? And how will they believe in Him of whom they have not heard? And how will they hear without a preacher (messenger)? And how will they preach unless they are commissioned and sent [for that purpose]? Just as it is written and forever remains written, “HOW BEAUTIFUL ARE THE FEET OF THOSE WHO BRING GOOD NEWS OF GOOD THINGS!” [Is 52:7]
