I know it was probably an oversight, but John Wesley was also postmil.
The one thing he was off his flippin' rocker about.
Christ's return to a totally depraved world, given totally depraved inhabitants, is not a sign of failure at all. It sounds more like a sign of reality.
That would be like calling the crucifixion a failure.
So there is no hope at all for anyone, this side of the parousia? If so, then WHY BOTHER "praying for our troops to win?" Where sin abounds, in your view, this is no room for grace, but only an inescapable black hole sucking all down to destruction. Except for maybe a few etherial saved "souls" floating like soap bubbles in detached abstraction over the drain.
So why did the Word need to become flesh if only "spiritual" things are relevant? If your statement is indeed a true reflection of your theology, then you are preaching gnosticism, not Biblical Christianity. For there is no real-world redemption in your theological construct. You have nothing to offer a desperate world beyond personal "gnosis" -- and the hindus can offer that.
