These evil beings are under the guidance and power of Satan, a malignant leader whose mind and will and heart are totally corrupt. These demons try to blind humans to the truth. In addition, as Jesus warned, demons snatch away the seed of the gospel while it is being proclaimed, diverting the attention of hearers by the alluring vanities of this life. Consequently, unbelievable as it may seem, the fate of the cosmos is being decided here on earth. Our small planet is the battleground between good and evil, the kingdom of light and the kingdom of darkness.
Earth Is The Schoolhouse Of The Universe.
Third, this insignificant planet is the schoolhouse of the universe. By observing the things that transpire on the human level, angels and demons are learning about the goodness, power, and grace of God. To the intent that now the manifold wisdom of God might be made known by the church to the principalities and powers in the heavenly places. The content of God's inexhaustible wisdom lies beyond the grasp of our minds. Yet Paul was assuredly affirming that non-human beings are now being taught pivotal lessons about God as they watch the drama of redemption unfold on our earth.
