Faith is impossible to avoid. Faith in science or your own reason is still faith. Faith in the scientific method is also faith. It’s not faith versus reason but faith versus faith. Any system of belief begins with a presupposition that cannot be proven—a contingent fact. All knowledge is contingent--it commences somewhere with a premise.
Faith is merely trusting in what one has good reason to believe. It isn’t the same as blind faith which is for no reason. Faith is rational and not contrary to logic. You cannot disprove God either, so it’s a matter of faith to deny His existence. That’s because it’s impossible to prove a universal negative No amount of evidence will convince a person to believe something he doesn’t want to.
There is no “smoking gun” evidence either way; no amount of evidence will convince a person beyond a shadow of a doubt. But the fact is, is that there is evidence from science, scripture, history, literature, logic, philosophy, and personal testimony. “But a person convinced against their will is of the same opinion still.”
The Bible’s authority is self-attesting and appeals to no higher authority than itself; otherwise, it couldn’t be the final arbiter of truth but science or philosophy would be. You must appeal to some authority and secularists appeal to their own reason and put their faith there intentionally rather than in God. Thus, you can become a Christian without committing intellectual suicide or kissing your brains goodbye. In summation, we’re all People of Faith, faith in what is what matters and differs! Soli Deo Gloria!
