The simple truth is that no single individual can possibly come close to understanding what this ‘God’ thing truly is. That would be even more inconceivable than a single cell in a person’s body understanding the whole body to which it belongs. It is a part of something greater and it exists for the greater good. What more can it/we really know?
We do not even fully understand ourselves. How much more incredibly complex is God than ourselves? [Isaiah 55:9]
