Oh yeah, this one occurred to me a few years ago but I was reminded by a particularly muddle-headed sermon recently: (Any sermon which contends that God chose the Jewish people as His own Special Chosen People to work with for a few thousand years, just so that He could cynically use them to demonstrate to the rest of the world that they completely let Him down, and therefore they should all go to Hell for being unable to keep his utterly impossible Law, is going to end up in a big bucket of Fail as far as I'm concerned. Unfortunately, such a view is not so much widespread as omnipresent.)
So, you know how your God demands that you forgive your enemies unconditionally, right? And by unconditional forgiveness, we mean not waiting for them to make the first move but deciding to unconditionally forgive them there and then, yes? They don't have to accept it, you just have to forgive them anyway, right? Because if you don't forgive them their sins, God won't forgive you yours - I think that's in the Lord's Prayer, isn't it?
But you also say that He won't grant forgiveness to sinners until they repent and profess faith in Him. Suddenly they have to turn around and accept that forgiveness before they get into heaven. Talk about one rule for one and another rule for another. Are you guys being held to a higher standard than the God you serve? If so, that makes you morally superior to him.
Anyone who can get their way out of that one has clearly done their homework. Oh, and anyone who comes back with "Well, He is God and so we don't get to question anything ever" ... well, you can work out which camp they fall into.
