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.
The apostle, John, wrote, “Perfect love casts out fear.” (1 John 4:18) This was written by a man who, when the chips were down for Jesus, scattered in fear with the rest of the apostles. As Jesus tried to tell them of the need for him to die and be raised from the dead, something the apostles did not understand, he predicted they would all forsake him.
“You will all [i]fall away because of Me this night…. (Matthew 26:31)
Peter might have pumped his chest with bravado as he protested that others might leave Jesus, but he would never leave. (Matthew 26:32-33) But, Jesus knew better than Peter knew himself. He predicted that Peter, though swearing allegiance at that very moment, would deny him not once, but three separate times. (Matthew 26:34)
So great was the fear that overtook the disciples that they scattered after Jesus was taken by the Roman soldiers. Even Peter, who didn’t scatter, but stayed back to witness the interrogation, beatings, mocking and humiliation to which Jesus was subjected, denied that he knew him… three times.
Fear is a powerful emotion. It can overwhelm us and cause us to stumble from the path that we know is right. How do we overcome fear?
