There's the truth and reality that we can agree on - such as the existence of France -
and then there's the "truth" and "reality" inside your head.
There is Truth and there is Reality.
There is no degree of either.
Things either exist or they do not and are not real.
Things are either true or they are not, regardkless of have close to being true the erroneous concept may be.
In one's head, the spirit of mind could be true or false.
But there is never Reality in your head.
Reality is always "out there."
Reality is out there, where your seven senses tell you about it.
You construct an image that you believe corresponds to that real thing out there.
If you are wise, you do so using the Scientific Method.

God is all there is, ie; Reality itself... the whole external existence beyond our mind is the almighty God to which all life must bow:
...Truth inside our head, is the Holy Spirit, the image of God, almighty Reality, and is present inside our mind when our thinking correctly images the TRUTH, or the picture of Reality inside our mind.

TRINITY:
Our (1) Lord is Truth, in whose (2) Spirit of mind we must commit our lives, in order to face (3) Father Nature, the Almighty Reality, within which we all exist.
