What does the Bible say about being carnal and spiritual?

In Romans 7:14-25, Paul describes the struggle between the flesh and the spirit. He acknowledges that while the law is spiritual and good, he himself is carnal, sold under sin. This emphasizes the condition of humanity in Adam, where our flesh cannot produce spiritual obedience. The Spirit reveals to us our sinful state, leading us to seek salvation in Christ rather than in our own efforts. It is through the Spirit that we can understand and obey the spiritual law of God, moving beyond the limitations of our flesh.
