It is the glory of God to conceal a matter. Surely, no creature will ever be able, even when exalted to heaven, to comprehend all the thoughts of the Creator. We shall never be omniscient — we cannot be. God alone knoweth everything, and understandeth everything. But how much more of authentic truth shall we discern when the mists and shadows have dissolved; and how much more shall we understand when raised to that higher sphere and endowed with brighter faculties, none of us can tell.
Probably, things that puzzle us here will be as plain as possible there. We shall perhaps smile at our own ignorance. I have fancied sometimes that the elucidations of learned doctors of divinity, if they could be submitted to the very least in the kingdom of heaven, would only cause them to smile at the learned ignorance of the sons of earth. Oh! how little we do know, but how much we shall know! I am sure we shall know, for it is written, “Then shall I know even as also I have known.”
