Is the world limited to what we can see and touch, or is there a spiritual realm operating beyond our natural sight? Why are some people comfortable believing in angels but hesitant to believe in God, demons, or spiritual warfare? In Episode 6 of Theology in Plain Words, Dr. Susan Agbenoto and Faith Simplified author Aaron Armstrong explore what Scripture teaches about angels, demons, Satan, and the unseen spiritual world. The Bible presents angels as created spiritual beings who serve God, while demons are rebellious spiritual beings who oppose God’s purposes. Satan is powerful, but he is neither God’s equal nor beyond God’s authority.Drawing from Ephesians 6:10–12, they discuss Paul’s teaching that our struggle is not merely against flesh and blood, but also against rulers, authorities, cosmic powers, and spiritual forces of evil. Some visible conflicts may have an unseen spiritual dimension, which is why believers must remain prayerful, discerning, and spiritually prepared. This episode also offers an important balance. Christians should not deny the reality of spiritual forces, but neither should they assume that every problem, illness, disagreement, or hardship is caused by demonic activity. Biblical discernment helps us recognize spiritual opposition without becoming fearful, fixated, or careless in our conclusions. Most importantly, believers do not face the unseen realm without authority. Through Jesus Christ, we can resist the devil, confront spiritual opposition, and stand against forces seeking to hinder God’s purposes. Our confidence is not in our own strength, but in Christ, under whose feet all powers and authorities have been placed.
