The theist confesses freely that the importance of the moral end is a thing that the facts of life, as we now know them, will never properly explain to us.

It can at present be divined and augured only; its value is one of promise rather than of performance; and the possession itself is a thing that passes understanding.

It belongs to a region of mystery into which neither logic nor experiment will ever suffice to carry us; and whose secrets are beyond the reach of any intellectual aeronaut.

But it is a part of the theistic creed that such a region is; and that the things that pass understanding are the most important things of life.

Nothing would be gained, however, by postulating merely a mystery--an unknowable.
