Christian apologist Richard Howe offers the following response to the atheists’ claim that they need more evidence:
When I was debating this atheist, I asked him, ‘what would convince you there is a god?’ He said “If all the chairs in this room rose up, flew against the back wall, and spelled ‘I am here — God’ then I would believe there is a god.” I am not convinced he would believe if this happened. If he was consistent philosophically, his atheism would have some way of trying to account for it, that there is some type of natural law that we have not yet discovered. Why do I think this? Because they already do this in things they observe, like the DNA molecule.
Suppose that all the chairs did rise up and float against the back wall and spell out “I do exist — god” and this atheist does believe there is a god. Suppose then that he goes out and tells others that he believes there is a god. They ask him why, and he tells them about the chairs. Then the same thing happens to them….the chairs rise up and float against the back wall, and they believe there is a god. And so he goes out into the world and everywhere that he confronts an atheist, chairs rise up and float against the wall. Until finally, he tells a person that he believes in god, and the person asks why. He tells the person he believes because chairs rise up and spell things against the wall, saying that there is a god. The person then responds, ‘Oh, that happens all the time. That’s no evidence for god; that’s always happening.’
So the atheist complains that God is not giving enough miraculous evidence for His existence, but if you give enough evidence for His existence, they just take the abundance of that evidence and call it a natural event. Ask the atheist, ‘DNA has information. Do you think that at least shows there is an intelligence?’ They say, ‘No, DNA is a natural thing. It’s in everything.’ Thus if there is not enough evidence, the atheist complains, but if there is an abundance of evidence, they redefine the evidence and call it natural.
I believe Howe is correct. For many who do not want to believe, it is not for lack of evidence, but an act of the will. In such cases, the atheism is non-falsifiable.
The purpose of apologetics is not to argue someone into the kingdom, which cannot be done. Rather it is to take away the excuses of the non-believer so they will realize their reasons are indeed excuses, not valid reasons. Another main purpose of apologetics is to reinforce accurate biblical teachings to Christians so they will not slide into heresy, which is all too common among Christians.
