In Matthew 12:22-37 Jesus is accused of exorcising demons by the power of Satan. The entire episode raises an important question: is spiritual conflict, or spiritual warfare, real?
The Apostle Paul addresses that pretty directly in the last chapter of the book of Ephesians, where he closes out the letter by writing these words:
“Finally, be strong in the Lord and in his mighty power. Put on the full armor of God, so that you can take your stand against the devil’s schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.”(Ephesians 6:10-12)
Paul’s final word to the believers here is that there is a spiritual conflict, and the struggle is real.
So, do I believe in real spiritual forces that stand against God and His people? Absolutely, yes. The Scripture is replete with that idea, from Jesus’ encounters with demons to hints of demonic forces in the book of Daniel and Revelation.
Because of that, we must arm ourselves appropriately for such a struggle by relying upon the strength of the Lord and not our own strength. We all know that our human strength is limited, but that God’s strength is unlimited.
As it says in Psalm 73:26, “My strength and my heart may fail but God is the strength of my heart and my portion forevermore.” Or as it says in Isaiah 40: “Even youths grow tired and weary, and the young stumble and fall; but those who hope in the Lord will renew their strength.”
If we want victory, we must rely on God’s strength.
Paul says that we do this by arming ourselves appropriately in what he terms “the armor of God.” Notice that this armor is made by God and has its source in God. The goal of relying on God’s power and arming ourselves with His armor is so that we can “take our stand.” This tells us something important here: the armor and our role in the conflict is primarily defensive. Paul helps us understand how to defend ourselves against the onslaught of the devil and his forces.
What are those forces? Well, Paul lists out several aspects of them:
- they are not flesh and blood
- they are rulers and authorities
- they are the powers of this dark world
- they are spiritual forces in the heavenly places
We are not talking about people here, but about forces running higher and deeper than mere human force. Certainly, we are talking about the devil and spiritual forces. Jesus faced them and the early apostles faced them and we too will we face such demonic powers.
The words of 1 Peter 5:8-9 are still true for us: “Your enemy the devil prowls around like a roaring lion looking for someone to devour. Resist him, standing firm in the faith, because you know that the family of believers throughout the world is undergoing the same kind of sufferings.”
Returning to Ephesians 6, we must also remember that along with the purely spiritual forces against us, Paul also speaks to the reality of other powers at play in the world.
There are kings and rulers of the world, there are social-cultural dynamics, there are hidden powers of sin and injustice that seem to have super-human power within societies and the world. The Ephesians believers lived in a context dominated by worldly living, idolatrous religion, and perverse customs and practices. These, too, Paul says will often stand against us as believers. They are impersonal but often used by personal beings, whether human or demonic, to oppose God’s people.
Sometimes this evil is readily apparent, but at other times “Satan himself masquerades as an angel of light” (2 Corinthians 11:14). This requires even more vigilance. Therefore, the attack comes in ways that might be appealing or enticing or just plain nice to be around. Yet, as Eugene Peterson writes, “Paul is calling us to be alert to the evil that, in fact, looks like the good.”
“Believers,” Paul says, “this struggle is real. See it. Name it. Prepare yourself for it. And stand in the face of it.”
