The doctrine of irresistible grace teaches that whatever God decides will inevitably happen, specifically with the salvation of people. It states that no person can resist if God calls them to Him. The heart of this doctrine is the question of “why some people believe and have a relationship with Christ and some do not?” It can’t be because they are smarter than others or more capable, because then it gives them reason to boast that they saved themselves. So it has to be that God revealed Himself in a certain way to some and not others. So doesn’t that mean God chooses some people to bring to salvation and not choose others?
We’ve established that God must reveal Himself more to some than He does to others, because we don’t see everyone come to Christ. But that doesn’t mean that God doesn’t reveal Himself to everyone to some extent. This is called general revelation: the idea that God reveals Himself to everyone through nature, our conscience, and history. Romans 1:20 “For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.” So everyone has the ability to come to Christ because He reveals Himself in creation, and no one can blame God for not giving them a chance. So why does He choose to reveal Himself more to some people than others? No one can truly say. It’s important to remember the story of Job; no person can ever fully understand God’s plan and knowledge.
