[Sons to Glory!]

If we look at John 14:6, "I am the way, the truth and the life - no one comes to the Father except through Me", "truth" here is ἀλήθεια (alētheia) which is Strong's reference 225. Strong's definition is " truth, but not merely truth as spoken; truth of idea, reality, sincerity, truth in the moral sphere, divine truth revealed to man, straightforwardness."

So this is one place where I don't see much issue with using the word "reality" for "truth" - they are basically synonymous.

But reality does also seem to carry the meaning of a fuller, broader picture. I kinda think of the Matrix movie, where they thought they were living a true life, but in reality they were hooked-up to a life-sucking machine.
