Imagine your phone's battery is dying. A powerful nuclear reactor is near you. It's got all the energy you need but can you charge your phone from it?
No, you need a transformer.
I believe that God is such a force that people would really die if they saw God, or be in the presence as His full power. Just as God said to Moses. Noone can see me and live.
But you would expect from the creator of the universe to be so powerful!
The thing is we are humans and understand this material world where we live. The material world and the forces and energies we understand are between 3-5 % of the universe. The other 95-97% we have no idea about.
Similar with God, we say person because we are persons, and know what a person is but we can not even imagine or perceive his nature. Entity, spiritual being, inteligence. He reveald Himself to us through things we know and can understand. It is like explaining light or color to a person who was born blind.
