One has tasted of the fruit of the tree, and the happiness that comes, when any does come — and often enough it fails to return in an acute form, though its form is sometimes very acute — is not the simple ignorance of ill, but something vastly more complex, including natural evil as one of its elements, but finding natural evil no such stumbling block and terror because it now sees it swallowed up in supernatural good. The process is one of redemption, not of mere reversion to natural health, and the sufferer when saved, is saved by what seems to him a second birth, a deeper kind of conscious being than he could enjoy before.
