Reality is now. It’s everything, everywhere, every thought, emotion, or action happening at this moment in time.
Truth is a quality that something is in (or has been in) the set of reality. Anything that is true is part of reality. Anything that is false is not. Truth includes the past and present. The future is only a fear, hope, or expectation, unless you have the gift of prophecy. The future is Shrodinger’s cat. It’s both true and false at the same time, until it happens.
Faith is belief. I have faith that you will ace your test. That means that I believe that you will ace your test. But not out of pure luck, because I know that you know the material. So you cannot have faith in something that you do not believe to be true. Faith is based on knowledge. If what you know rules out said thing from being possibly true, it’s impossible to have faith in that thing. If you are terrible at math and didn’t study or do any homework, how can I have faith that you will do well on your test? I can’t. Faith does not exist outside of truth.
For instance, if you think that science is true, and you think that faith is a set of things that are also true, but that are outside the set of science, that’s not possibly the case. Two things that contradict each other could not possibly be true at the same time. It’s like saying I am wearing a yellow jacket that is red. I believe that if we unravel the shortcomings of science, we could see a happy marriage of faith and science. With the jacket comparison, I’d be wearing a yellow jacket with red stripes.
