The second day of the Strange Fire conference began with John MacArthur preaching a message titled “Testing the Spirits.” It was based on 1 John 4: “Beloved, do not believe every spirit, but test the spirits to see whether they are from God…”
There are many places in the New Testament where we are told to test all things and this is critical because Satan and his demons exist and because they operate a kingdom of lies that dominates the world. Satan has been allowed to run loose in this world and he and his agents are disguised as angels of light. We should not be surprised that Satan operates 99% of the time in false religion, in lies and deception. He is not the one behind the corruption in sinful society—the flesh takes care of that. He is behind the false systems of belief that pervade this world.
