Right. Tulkas is never around when you need him.
No kidding. I think the Eldar would have said the same. "Okay, you say you're on our side ... but where are you now?"
Tolkien's fictional spiritual world is a complicated mélange of Christian and Germanic-pagan. You can hear his Germanic heart singing, "Morgen rot, morgen rot!" with the Riders of Rohan, as his Christian intellect reminds us that the berserkergang is a bit ... barbarian ... not quite the thing ... kinda like we're supposed to know better, but ...
If there's an overarching theme, it's "Where were you when I needed you?" "If you're all that, what went wrong?"
It's the universal dilemma of humanity vs. our deities. It can only be "resolved" in Christ: in the incarnation of the Son of God, His passion, death, and resurrection, which subsumes/incorporates our suffering, death, and resurrection.
