For example, John Loftus, in his recent post on "Debunking Christianity" entitled "Can Prayer Change the Past? One More Time" sets a challenge before Christians to "pick any event in the past, announce that they are praying to change it, and then watch what happens." His argument is that if God lies outside of time, but hears the prayers of believers, then God can change the past, events like "the Holocaust, the terrorist 9/11 attacks, or any tragic event reported in the daily newspaper."
Besides the obvious question of how one would determine that God changed the past (given that the change would then be our past), Loftus' challenge is an example of either poor exegesis or faulty logic when it comes to the Scripture. Does not Loftus understand that God does not change and that the prayers that God honors are those in keeping with his will? In effect, what Loftus seeks to accomplish through his challenge is to put the burden on believers to prove the existence of God by having God answer a believer's prayer which is contrary to his will (something contrary to Scripture). This is no different than the logic used by those who in arguing against freedom of the will in light of predesitination are willing to suppose that God predestines the end but then fail to recognize that God ALSO presdestines the means to that end as well. Or better put, it can be likened to someone challenging another to prove a spouse's love for their mate by presenting evidence (or seeking to show evidence) that is contrary to love.
Let readers beware, that often what may appear to be fine sounding arguments at first by unbelievers (even those who set themselves up as previous believers or pastors), are easily untangled and found faulty when one takes the whole truth into account. Scripture shows that one of the tactics often used by those who oppose Christ is to try to set forth a half-truth as the whole truth. Those who want to avoid deception and become mature must learn to discern and then they will not fall to those arguments which are falsely set forth as high-minded wisdom and knowledge.
