Natural Man in 1 Corinthians 2:14-15

The natural man, as described in 1 Corinthians 2:14-15, is one who is unregenerate and therefore unable to understand the things of the Spirit. Paul writes that the natural man receives not the things of the Spirit of God, for they are foolishness unto him, neither can he know them, because they are spiritually discerned. This highlights the spiritual blindness and inability of the unregenerate to comprehend spiritual truths, which is a fundamental aspect of Reformed theology.

The natural man's inability to understand spiritual things is a result of his sinful nature, which separates him from God and renders him incapable of spiritual perception. This doctrine is rooted in the biblical teaching on total depravity, which asserts that humanity's rebellion against God has resulted in a comprehensive corruption of human nature. The natural man is not simply lacking in knowledge, but is actively opposed to the things of God, and therefore requires a supernatural work of regeneration to enable him to understand and receive the gospel.

This truth matters because it underscores the necessity of the new birth and the work of the Holy Spirit in illuminating the mind and heart to spiritual realities. The natural man's condition is one of spiritual darkness and ignorance, but through the gospel and the regenerating work of the Spirit, he can be transformed into a new creation, capable of understanding and embracing the things of God. Paul's statement in 1 Corinthians 2:14-15 serves as a reminder of the profound spiritual transformation that occurs when one is born again, and the resulting ability to discern and appreciate the spiritual truths of the gospel.
