Why do some people reject the truth of the Gospel?

The rejection of the Gospel stems from the inherent rebellion of the human heart against God. Jesus highlights that it is not a mere lack of evidence that leads to disbelief, but a profound spiritual blindness and an unwillingness to accept the truth that confronts their sin. This aspect of human nature signifies that without divine intervention and grace, individuals are naturally inclined to walk away from acknowledging Christ and the redemptive work He accomplishes. As believers, we must understand that this reality calls for us to rely on God's sovereign grace to open hearts to the truth of the Gospel.
