Why is the grace of God essential in overcoming Satan?

In Romans 16:20, the apostle Paul connects the crushing of Satan with the grace of our Lord Jesus Christ, indicating that divine grace is a critical factor in spiritual victory. This grace not only provides forgiveness of sins and reconciliation but also empowers believers for daily living and resistance against temptation. The grace of God equips Christians to act decisively in faith, enabling them to engage in spiritual warfare with confidence. Without this grace, efforts to combat Satan's schemes would be futile, as victory ultimately comes from God's strength operating through His people.
