Saint Ambrose on God's Omniscience

Nothing escapes God's knowledge. This is proved by the witness of the Scriptures and the analogy of the sun, which, although created, yet by its light or heat enters into all things.

— St. Ambrose of Milan

We should trust God, in all matters, even if we cannot understand the designs of Divine Providence at present. Be assured that in the fullness of time all things will be made known to us when we see God face to face in heaven.
