The real answer is the Trinity was meant to reconcile various passages in the Scriptures that weren't otherwise easy to harmonize together, and so we have this convoluted mess of a doctrine.
The Trinity is not parts btw. This is a common misunderstanding of the doctrine. It's one being that's somehow simultaneously three persons. Don't ask me how this makes sense, it doesn't to me.
