You are controlled by nature. It has covered your consciousness by making you identify with your particular body and mind. You are imprisoned. How can you think you are God? If God can be captured by nature then nature is greater than God, then nature is God.
I am not controlled by nature, I am under influence by nature. There is massive difference between control the influence. If I am controlled, it means I have no agency or will, I am like a robot or a puppet. If I am under influence, it means that I do have agency or will, but I have certain dispositions will lean me to certain action. These dispositions maybe conscious, subconscious or unconscious. When I became aware of any disposition that influences my actions, I have the power to override that disposition.
Now Yoga is based exactly on that premise that we can override our dispositions and ultimately bring the body, mind and nature fully under our control. If we were the same as the body, mind and nature, we would not be able to gain control of it. The fact is, we are not the same as nature or matter, we are conscious beings and have the power of seeing/knowing. According to Yoga this power is most expressed in the Buddhi(intellect) part of the mind and because it so similar to us, this is why the misidentification takes place and the Buddhi assumes itself to be sentient, feeling pain and pleasure and reacting to the stimuli in the world.
The aim of Yoga is to purify the Buddhi, much like cleaning the muck away from the surface of a mirror, so that it reflects the light of consciousness more clearly. The perfectly pure Buddhi leads to the perfect reflection of the self. Our buddhi is impure, and this is why our sense of self is unclear. Although we are infinite, perfect and divine beings, we do not feel this to be true. As we gradually purify our buddhi we will feel our self much more strongly. Then we will realize that we are indeed god.
To summarize: I am god, but I am just god under the influence of nature /matter. I am conscious of some influences, subconscious of some influences and unconscious of most influences. As I flirt between the different states of consciousness waking, dreaming and dreamless sleep I reveal more or less consciousness. As I evolve, more and more of my subconscious and unconscious influences will become conscious to me and I will be able to gain more and more control over them. Eventually, I will become the master of my body, mind and nature. I will enjoy the same glories that god enjoys. I am a god already, but I am in the process of remembering it.
So does god forget? No, god always remains god. As Yoga says, Ishvara never enters into space, time and causality. Ishvara is never bound. However his particles do get bound, but all these particles are identical to him and will eventually return to him.
I will never lose the sense of my self, even when I become a god I will remember every memory and every past life I have had, just as Krishna remembers all his past lives in the Gita.
Remember, you are speaking with a god right now. One day I will attain full realization and I will remember everybody I encountered and everything that was said to me, and there maybe scores to settle
