. . . Jewish monotheism acknowledges that God doesn't exist in a way that we humans would consider viable under the terms to "exist," or to be "existent." Monotheism use aniconic verbiage to speak of God's non-existence without thinking the fact that he doesn't exist is really much of a problem for him.
In one sense, Judeo-Christian thought requires the true believer to accept that God doesn't exist before they're ready to be initiated into belief in him.
True enough, most Jews and Christians are uninitiated theists. And in that sense they see themselves as opponents to atheists.
Nevertheless, those Jews and Christians who have been baptized into Christ through their faith in the tenets of atheism, are fully aware that God doesn't exist, but that not existing neither concerns God, nor encourages the true believer to forgo the unimaginable things he has in store for those who don't let the fact that he doesn't exist scare them into asking people like Moses and Paul to stand up as a stand in so they don't have to fear being in the very presence of a God who doesn't, technically speaking, exist.
Atheism is the first prerequisite to true, thoughtful, theistic faith. You don't have to give up one iota of your common sense, and we can say accurate, understanding that God doesn't exist, to become a full-fledged theist in good standing. In fact, if you do, you will be joining something like the cub scouts, rather than the boy scouts.
