the senses sustain resistance

Here is a quote that I think is EXTREMELY true:

“Disbelief is more resistant than faith because it is sustained by the senses” (Gabriel Garcia Marquez, Of Love and Other Demons).
I believe as a pastor and teacher that we are often tempted to provide sensational additives in order to captivate people and keep them. Which, I also believe, weakens faith. I’m totally convinced that faith is not at all sustained by the senses, which makes it appear weak, but ultimately isn’t. What do you think? What’s your sense on it?
