What does the Bible say about why sinners reject Christ?

The rejection of Christ by sinners is a profound theme in Isaiah 53 and is rooted in their carnal nature. The first reason proposed for this rejection is that Christ has no form or beauty that the flesh finds appealing (Isaiah 53:2). Spiritual deadness prevents people from recognizing the beauty and power of the gospel. They are unable to see the righteousness of God, manifested in Christ, due to their enmity against Him. As the scripture articulates, the carnal mind is enmity against God and cannot submit to His law (Romans 8:7). Therefore, when the gospel is proclaimed, the natural man finds it unappealing and foolish, leading to rejection. This stark reality continues to affirm that faith is not a product of human will but a sovereign act of God’s grace.
