This is a follow up to the article on the question, "What about those who have never heard?"
While this is surely an intriguing question, it is important to understand that a more pertinent question is, "How can I make sure that they will hear?"
Paul said this best in Romans 10:14-15:
"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? How will they preach unless they are sent? Just as it is written, "How beautiful are the feet of those who bring good news of good things!"
While it is reasonable to suggest that God does not leave any man without a witness, it is not unreasonable to suggest that the amount of that witness varies from person to person. For example, an individual who lives in a southern and conservative state in the United States is likely to be saturated with the Gospel and have ample opportunity to believe. God's witness would be strong and powerful in that individual’s life. Many of the southern states have a church on every corner, libraries full of Bibles, and people have the opportunity to freely believe in Christ without persecution. For an individual who lives in a remote place in the world, however, it may be the case that God's revelation isn't as prevalent or favored as it is in the "Bible Belt."
This is why Jesus' final command to His disciples--those who had the powerful testimony and revelation of God through His Son--was to "go" (Matt. 28:18-20). This is also why Paul said, "How beautiful are the feet of those who bring good tidings" (Romans 10:15). Instead of wondering about those who may never hear, an even better question is, "What can I do to make sure that they will hear?"
