Can we be certain of God s existence? The short answer is, no. If the question is whether we can have something like mathematical certainty or proof, we have to answer that question in the negative. There is no evidence, no proof or argument that can provide certainty that God exists for finite beings such as ourselves.
Such evidence, proof or argument would have to be built on premises that are 100% certain, and that kind of certainty is impossible for beings that are not all-knowing. The best we can do is to put forth evidence, proofs and arguments that suggest a probability that God exists – to show that the likelihood is more probable than not that God exists.
To this extent, doubt is the common experience of saints and sinners alike.
To put this another way: Can we be sure that God doesn’t exist? The only certainty is that we can’t be certain.
Many believers have doubts, and many nonbelievers have their own doubts.
