How do we know the concept of sin being an enemy is true?

The understanding of sin as an enemy is grounded in the teachings of Scripture, especially in Romans 6. The Apostle Paul explicitly states that sin is a transgression of God's law and poses a direct threat to our relationship with Him. Sin brings about death, as stated in Romans 6:23, and it is the root cause of all suffering in the world. This perspective invites believers to recognize sin not merely as a mistake but as something that opposes God's holiness and separates us from His presence. Through constant spiritual warfare, believers are called to resist sin and strive against it, echoing the urgency found in the warnings and teachings throughout the New Testament.
