[I]f you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. [10] For with the heart one believes and is justified, and with the mouth one confesses and is saved. [11] For the Scripture says, “Everyone who believes in him will not be put to shame.” [12] For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. [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!” [16] But they have not all obeyed the gospel. For Isaiah says, “Lord, who has believed what he has heard from us?” [17] So faith comes from hearing, and hearing through the word of Christ (Romans 10:9–17 ESV).

Question 60: Can they who have never heard the gospel, and so know not Jesus Christ, nor believe in him, be saved by their living according to the light of nature?

Answer: They who, having never heard the gospel, know not Jesus Christ, and believe not in him, cannot be saved, be they never so diligent to frame their lives according to the light of nature, or the laws of that religion which they profess; neither is there salvation in any other, but in Christ alone, who is the Savior only of his body the church.
