Dennis Prager talks about everything and anything on his radio talk show. I always enjoy listening to the topics that he brings up. One of the things that Dennis Prager often says about faith is that it is subjective. Can anyone prove or disprove the genuineness of someone's faith?
In Christianity, faith is only as good as the object of our faith. If I place my faith on something that is not deserving, say a rock, then no matter how genuine my faith is, that faith is delusional. Believing in something that is false does not make it true.
As a Christian, I have to first of all acknowledge that I am a finite being, with limitations trying to understand and reach out to an infinite God, a God who is not limited by time and space.
I have to put my trust in His Word which he has left behind as " a lamp to my feet, and a light unto my path" (Psalms 119:105). I have to put my trust in Him because He tells me so, and not to rely on my own understanding. (Proverbs 3:5,6)
I can only do these things with my faith. My faith makes it possible for my limited understanding to reach out to the One who is without limitations.
"And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him". Hebrews 11:6
