Many of us have believed at one point or another that God sees everything that happens on the earth. Thus, when evil happens, we assume that he saw and allowed the evil. The truth is that God sees and hears no evil other than the evil that happens to those in whom the Holy Spirit dwells, if they call God's attention to the evil through prayer. His all knowingness stems not from his eternal gaze, but rather, from the recordings in our soul. Our souls tell him who we are and what we have done. If God saw, heard, and allowed all the evil that has happened on the earth, he would have become a co-conspirator with Satan.
In fact, God is just as concerned about the evil brought to his attention as would any compassionate human. He wants the evil to end at least as much as the person experiencing the evil. But just as Satan acts and accomplishes his purposes through humans, God also acts and accomplishes his purposes through humans. When Satan's "army" is obedient to Satan's commands and instructions, and God's "army" is motionless and/or rebellious to God's commands and instructions, evil can take control of the earth.
God does not insist on governing and policing the entire earth because he gave us each free will for a good reason--so that we can be truly free. Those who so choose can be free of his guidance, free of his control, free of his supervision, free of his light, and free of his gaze. When the light is not on, God does not see. He allows us the choice to do and experience both good and evil.
Spiritually, the light is "on" when we choose to have God's indwelling Holy Spirit inhabit our solar plexus (the area immediately above the stomach). When the light is on, God can see us from his dwelling place and can keep watch. Like the monitor in an infant's bedroom, the light in the solar plexus marks us as people belonging to God, connects us to him, and empowers him to guide and protect us. The absence of light (a dark solar plexus), signifies to him that we have made a different choice that sets us apart from him.
When good eventually overpowers evil and heaven and earth become one, God will be God of all. Perhaps then God might be worthy of blame for any lingering evil that happens on the earth. But if heaven and earth are one, and God is God of all, he will have the capacity to anoint his people with an immunity to evil. Until then, when God's people see evil in the earth, they are compelled to act in defiance of that evil. Because God who sees no evil and hears no evil, relies on us whom he has empowered by his indwelling Holy Spirit, to see, hear and obliterate evil at its foundation.
Choose today to obliterate evil at its core. Don't wait until someone six months from now sees the evil and acts in response. It is much more practical to remove and destroy an acorn to prevent it from growing, than it is to try to root out an oak tree!
