Lightbulb Sun

After church yesterday, I was thinking about truth.  These days people seem to think that truth is relative, that it can be whatever you want it to be.  I personally find the idea silly.  Truth is truth.  If you look it up in the dictionary you will find these definitions of truth: "the true or actual state of a matter", "conformity with fact or reality", and "a verified or indisputable fact, proposition, principle, or the like".  Do any of those definitions make it sound like truth could be whatever you want?  That I could have my truth and you could have yours and we could both be right?  I don't think so.  You can say that grass is blue all you want, but that won't make it true.  You can even believe it's blue.  And maybe when you look at grass, it really does look blue to you.  But guess what?  That still doesn't mean that grass is blue.  It might mean you're colorblind though.  And you can tell me the sun is actually a giant lightbulb, you can believe it with all your heart.  But the sun is not a lightbulb.
