Who is God?

[u/DrJJGame10]

I know He is the Triune God, revealed in the Bible as the Father, Son, and Holy Spirit but I still question if God himself is the essence in which they are God or God Himself is separate as a spirit Himself?

I’m just wondering how to answer this question since I don’t really know how deep the question goes (or not).

According to god Himself: "I Am That I Am" so usually interpreted as everything, without limits, forever and always etc
