From R.C. Sproul in Be Still, My Soul (25 Classic and Contemporary Readings on the Problem of Pain):
Things may appear to be without purpose or meaning. Their ultimate purpose might elude us for the present. Yet if we fail to see purpose in what happens, we must remember that our view of things is limited by our earthly perspective.
An important slogan in theology is finitum non capax infiniti. This means, “the finite cannot grasp the infinite.” The limit of our comprehension is the earthly perspective. We do not have the ability to see things sub specie aeternitatis — “from the eternal perspective.”
The eternal perspective belongs to God.
