I'd like to keep this thread centered on a single topic. That's probably like asking for a miracle, but I'm asking anyway. A common non-Calvinist assumption is that ability limits obligation - that is, if we are unable to do a thing then God does not hold us accountable for not doing it. A common example is God's command that all men everywhere should repent. The assumption goes like this - since God requires all men to repent then all men must be able to repent. Can this assumption be proven? I think it can easily be disproven, but I'd like to hear from some of you non-religionists (JUST KIDDING!!) first.
