You can have a God concept where God is all powerful and then go through something like a divorce and develop a God image where is cruel and uncaring. satan is constantly trying to do things to change our God image. The enemy can't dethrone God in heaven but he endeavors to dethrone Him in our mind. We want to be very wise about this. Our God image needs to be consistent with our God concept.
James 1:13-15 Let no one say when he is tempted, “I am being tempted by God”; for God cannot be tempted by evil, and He Himself does not tempt anyone. But each one is tempted when he is carried away and enticed by his own lust. Then when lust has conceived, it gives birth to sin; and when sin is accomplished, it brings forth death.
