I know the answer so let's see how many of you know.
The bible says we are made in the image of God, God is triune, thus we are triune. In fact the entire universe is triune...time has 3 parts (past, present, future), mass/space (length, width, depth) etc.
Body is one part, the question is then what are the the other two? I'll give you a hint. The bible says only God knows the difference between the last two, "not even the angels know".
