From Major Ian Thomas's teachings.
God to a man is as unconditionally necessary as oil is to an oil lamp. Without oil in the lamp, we have an oil lamp, but it won’t function as a lamp. Likewise, if you detach a human from God, you will still have a human form, but it won’t function as a human.
The only thing needed for an oil lamp to function as an oil lamp is to put oil in it. Then too, the only thing left for a human to act like a human is to put God within it. Oil in the lamp doesn't ask the lamp to try harder. Likewise, God, back in a human, isn’t so that humans might try harder.
Oil is only in the lamp so the oil can be oil, functionally. And God put back into a human is so God can be God, functionally. In other words, the spiritual new birth is designed to let God so function through a human that everybody recognizes that God is home.
Now God is in business, God Himself in the human, being.
