I think it pretty easy to succumb to Lennon’s anger if we have a bad and uninformed portrait of God. And surely a dominant portrait of God throughout history, or even the portrait of God to many Christians, is that authoritative master — quick to coerce, condemn and cast out; and slow to hold, help and heal.
You have reminded me of my old chum Mikhail Bakunin, that fiery anti-theist, who said of Voltaire’s quote:
, Idealism and Materialism, p.62"][The Idealists] say in one breath: “God and the liberty of man,” or “God and the dignity, justice, equality, fraternity, and welfare of men,” without paying heed to the fatal logic by virtue of which, if God exists, all these things are condemned to non-existence. For if God is, he is necessarily the eternal, supreme, and absolute Master, and if such a Master exists, man is a slave. Now if man is a slave, neither justice, nor equality, nor fraternity, nor prosperity is possible for him.
They (the idealists) may, in defiance of sound sense and all historical experience, represent their God as being animated by the tenderest love for human liberty, but a master, whatever he may do, and no matter how much of a liberal he may want to appear, will nevertheless always remain a master, and his existence will necessarily entail the slavery of all those who are beneath him. Therefore, if God existed, he could render service to human liberty in one way only — by ceasing to exist.
A zealous lover of human freedom, deeming it the necessary condition of all that I admire and respect in humanity, I reverse Voltaire’s aphorism and say: If God really existed, it would be necessary to abolish him.
I have to agree with Bakunin’s summation here. If God were that master, I’d probably feel morally obliged to accompany Bakunin and the anti-theists in that endeavour to dethrone him. But I do not concede that God is necessarily that “…supreme and absolute Master”. For God, “truly animated by the tenderest love for human liberty” does not coerce, he does not decree and he does not lord over others. Has not Yeshua taught us that no one is beneath God? God discards the pagan portraits that we erect for him (the same fallen “glory” that we would have of ourselves), and he lives amongst the Least — to be beneath even the poor, the oppressed, the sick and the marginalised — to serve humanity and its most vunerable, humbly and meekly. Servitude is the true glory of God.
Denying Bakunin’s premise of an authoritative God, Anthony de Jasay so forcefully explains how our servitude is coherent with liberty: “…freedom is most perfect when all are servants (more perfect even than if all were masters)… It is not the condition of servitude which contradicts freedom, but the existence of masters…” (just to clarify, de Jasay is not arguing for an anarchical theism). And if we lock in the portrait that Yeshua taught and modeled (one of universal, unconditional, unlimited, self-sacrificial, humble servant-love) we’ll probably have more of a capacity to recognise the value of universal justice, equality, fraternity and prosperity and less difficulty (not no difficulty) with experiencing suffering. The more we see God like Bakunin’s absolute Master the more we will (justifiably) succumb to Lennon’s evident bitterness.
Regarding the OP, I don’t believe pain is helpful for belief.
