How do we know that spiritual warfare is real according to the Bible?

Spiritual warfare is a foundational concept in Christian theology, underscored by various scriptures including Ephesians 6:10-12. In these verses, Paul warns believers of the need to engage in this warfare, indicating that our struggle is not against flesh and blood but against spiritual forces of evil in the heavenly realms. This illustrates the reality of an unseen spiritual battle that every Christian participates in, emphasizing the necessity of divine assistance through God's armor. The imagery of armor suggests that Christians are to be equipped and prepared for the inevitable challenges and temptations they will face in their spiritual journey.

Moreover, the reality of spiritual warfare is evidenced by the call to prayer and reliance on God's strength through the Holy Spirit. Just as a soldier relies on their armor and training, Christians are called to seek strength from God, recognizing that their resources for victory in this battle come from Him. This ongoing conflict against sin and evil is not only a personal struggle but also a communal one, as believers are called to support one another in this fight, standing firm together in faith. Thus, Scripture provides a robust framework for understanding the seriousness of spiritual warfare and the strategies needed to triumph in it.
