Atheist claim nothing Christians say or do is sufficient to overcome the threshold of doubt they have established for themselves. This is true. Christians need to understand there is no path to certainty in the atheist frame of reference. No matter how may tests are done, nor what arguments are contrived, there must always be the possibility of doubt. Similar to a court of law, if the guilt of the accused cannot be proven beyond the shadow of a doubt, the accused must be given the benefit of the doubt and be deemed innocent. But the atheists ploy of setting the threshold of proof so high it cannot be breached leaves them with nothing that can be proven. In short, atheists by the tactics they have employed, leave themselves nothing to believe in but their own opinion. In short, Christians are at the very worst, are on par with an atheist. We are free to have faith in our own opinion, as they are. On the other hand Christians are free to be convinced by the logic of their arguments and evidence knowing all atheists have, is their opinion.
