Everything is a test

It’s hard to conceive of this, but everything that happens to us, and everything that we do with what happens to us, is a test, a probing by the Almighty, to see what we will do in every instance, even though He knows all. Wait! How is this possible?
If He knows all, what is the point? We cannot see as He sees, understand as He understands, how our free will interacts with His mercy, or how His foreknowledge affects or doesn’t affect our choice. We cannot grasp how He can create beings like us, indeed how He can create a whole universe of free agents that all move within and have their being in Him, yet that is what He has done. There is nothing that happens to us, and nothing that we do about it, that is not observed, weighed and written down by the Almighty, for His unknowable purposes.
Yet through all this, one fact remains: He loves us.
