Paul also makes it very clear in Romans 8:10 that the physical body, mind / intellect, and the heart (which is evil - Jeremiah 17:9) has been rendered helpless because of the original sin; consequently, the Believer trying to overcome by willpower presents a fruitless task. Only the Holy Spirit can mortify the deeds of the flesh and make us what we ought to be (Romans 8:13). This means we cannot do it ourselves. Once again, He performs all that He does within the confines of the Finished Work of Christ (Romans 8:2).
If a Christian will and their efforts to live for God is in anything except Christ and the Cross, i.e., Finished Work, The Blood of Jesus (Romans 8:2), Satan can override your will and force you to do things you don't want to do and trying not to do (Ephesians 6:12). Jesus said deny yourself and pick up your cross and follow me (Luke 9:23).
Remember our bodies are dead and useless to God. The heart is prone to wander away from God's love and eat from "The Tree of Knowledge of Good and Evil." The reason why the body is dead is because of the effects of the fall has made us totally incapable of yielding spiritual obedience on a regular basis (Jeremiah 13:23). So there must be a source outside of myself that helps me to enter into sanctification which is the Holy Spirit (Romans 8:13).

The Holy Spirit, He Works strictly within the parameters of the "Finished Work" i.e., "the Cross of Christ", which demands that our Faith be exclusively in the Cross of Christ. The reason is simple, that's were the price was paid, and the victory was forever won (Romans 6:1-14; 1 Cor. 2:2; Gal. 5; Gal. 6:14; Eph. 2:13-18; Col. 2:14-15).
For whatsoever is not of faith is sin. (Romans 14:23)
The Law Of The Spirit Of Life In Christ Jesus gives the Believer victory over the world, the flesh, and the Devil.
Victory over the world: Galatians 6:14 ; 1 John 5:4
Victory over the flesh: Galatians 5:24
Victory over the Devil: Hebrews 2:14 ; Colossians 2:15
How does a Believer maintain faith exclusively in Christ and the Cross? By just believing in Jesus (who He is) and what He accomplished at Calvary Cross. Romans 4:5 - Galatians 2:19-21 NKJV - 1 Corinthians 1:18-25 NKJV - Colossians 2:11-15 NKJV
