Why is understanding the natural and spiritual man important for Christians?

Understanding the distinction between the natural and spiritual man is vital for Christians as it underscores the transformation that occurs at salvation. The natural man is spiritually dead, unable to know or please God, whereas the spiritual man has been given life by the Holy Spirit and possesses a new nature (2 Corinthians 5:17). Recognizing this reality not only strengthens a Christian's identity in Christ but also emphasizes the importance of the new birth, reinforcing doctrines of grace central to Reformed theology. Moreover, it highlights the profound mystery of God’s revelation, as spiritual truths cannot be grasped by human reasoning alone. As Paul mentions in 1 Corinthians 2:10, 'God hath revealed them unto us by his Spirit,' indicating that spiritual understanding comes from divine revelation, not human effort.
