But we are three persons ourselves....Triune beings.....Body Soul and Spirit....so it is not difficult to grasp God as 3 persons of the Godhead.
Additionally.........I am a women....a mother....and once a wife......three defined differences yet one ‘person’.
Just as God is in the Trinity yet one.
I do not consider my spirit or my soul to be people.
I consider those to be a “spirit” or a “soul,” respectively.
