What causes people to reject Christ?

The rejection of Christ is rooted in several factors, primarily spiritual blindness and self-righteousness. As stated in Ephesians 4:18, individuals may be alienated from God due to ignorance and hardness of heart. They often pursue their own righteousness, believing themselves capable of earning favor before God, which blinds them to their true spiritual need. Additionally, worldly desires can distract from the spiritual truths of the Gospel. As the natural man focuses on earthly pleasures, he fails to see the worth of Christ, resulting in the rejection of His saving grace.
