Why is the concept of spiritual warfare important for Christians?

The concept of spiritual warfare is significant for Christians because it highlights the reality of an internal struggle that every believer faces. This warfare is illustrated in Rebecca's experience of having twins wrestling within her, symbolizing the conflict between the old man and the new man—a theme emphasized throughout Scripture, especially in Romans 7 and Ephesians 6. Paul urges believers to put on the full armor of God to stand against the spiritual forces of evil. Recognizing this warfare allows Christians to understand that their struggles are not merely physical or emotional, but deeply rooted in their spiritual lives, leading to a reliance on Christ for victory.
