What does the Bible say about the struggle between the flesh and the spirit?

The Apostle Paul describes in Romans 7:22-24 the profound internal struggle faced by believers, highlighting the tension between the new nature imparted by the Holy Spirit and the remnants of the sinful flesh. Regeneration does not erase our sinful nature; rather, it introduces a new divine principle within us that fights against the law of sin. This results in a continual battle in the believer’s life, where the realization of our wretchedness can lead to a cry for deliverance from this body of death. The believer is painfully aware of the lure of earthly temptations and recognizes that the flesh offers no help towards holiness.
