We should listen to God's revealed will. For He has made "known to us the mystery of His will" (Ephesians 1:9) and made it clear through Christ so that it might be preached.
This is revealed to us in the way Paul says "those whom He predestined [elected and foreordained] He also called" (Romans 8:30). God does not call without means, but through the Word. For He has commanded "that repentance and forgiveness of sins should be proclaimed in His name" [Luke 24:47]. St. Paul also testifies in a similar way when he writes, "Therefore, we are ambassadors for Christ, God making His appeal through us. We implore you on behalf of Christ, be reconciled to God" (2 Corinthians 5:20). The King calls the guests that He wants to have at His Son's wedding through the ministers He sends out (Matthew 22:2-14). He sends some at the first and some at the second, third, sixth, ninth, and even at the eleventh hour.
If we want to think about our eternal election to salvation helpfully, we must hold strongly and firmly to this truth: just as the preaching of repentance is universal, so also the promise of the Gospel is universal, that is, it belongs to all people. For this reason Christ has given these commands: Repentance and forgiveness of sins should be proclaimed in His name to all nations. (Luke 24:47) (paragraphs 26-28)
