Why phrase this in a negative sense? Motivated by the negative emotion of fear. Why not faith motivated by hope, or optimism? Or motivated by seeking something that transcends the mundane human experience? That it is within humans to seek something profound, or as @treco so beautifully wrote about the human desire to to seek answers to the big questions, or to seek something greater than ourselves. This is a position of humility, which can be also be a character strength.
This focus on fear is a bit like a religious person saying “there are no atheists in foxholes,” as in fear gets us all in the end. There is a form of religious pride in that idea, right? Why assume that belief or lack of belief it necessarily tied to fear as a primary motivator? This idea makes the person who lacks belief more courageous? More able to bravely look into the void? There is a form of pride in this too, is there not? At least maybe be open to the idea that you’re describing “most” people of faith as weaker than yourself.
