Very often the Gods use energy we give them to help the situation here on Earth. Energy is not all the same. The location on the astral matters a lot.
For example, suppose you want to move a piece of paper off a table. If you stand on the other side of the room and blow on it, that will take a lot of energy! However, if you stand right in front of it, you can blow gently and it will move easily. The paper is Earth. We are near it and the Gods are far away, so our energy is much more efficient than theirs at affecting Earth. When we "give" energy to the Gods, it doesn't mean that it suddenly becomes equivalent to their own. It just means that it's under their control, but it's still our energy, right here on Earth, in our astral dimension.
