But take care not to err in the other extreme: we know _in part_, and are always to know in part only. Our knowledge of allowed and enjoined things, though ever increasing, shall never be perfect on this side of the grave. We are to augment it as much as we can, but we must stand really face to face with Christ, before we see Him as He is. Our grossness must be refined, our souls and minds wholly transformed, and our bodies glorified, before we can fully perceive and appreciate the Holy Spirit. We must be in heaven to know thoroughly what heaven is. We must have Christ for our audible teacher, and angels for our prompting fellow scholars, and the eternal records for our books, and all time spread out before us as a map, before we can learn _perfectly_, what we are to spend this life and exercise the Spirit of knowledge in acquiring _in part_. And even then, as I said before, there are things which we shall not be able to grasp, or fathom, or perceive thoroughly. We shall never see GOD the Father visibly; we shall never comprehend altogether a Being without beginning or end; we shall never be omniscient or omnipresent. GOD will treat us as trusty and privileged friends, and reveal to us much that is not revealed here, and give us new powers of understanding it. But He will not open to us all the workings of the Divine mind. He will not transform us into gods, nor even into angels. We shall still be finite human beings, of limited understanding and limited knowledge. The things which concern us we shall know fully; the things which concern us not, we shall not know; just as the angels desired once to look into, but were not able, the mysteries (which did not concern them) of our redemption. Well, then, if there is to be holy ground in heaven, which we must not tread on with the shoes of idle curiosity; if there is to be there a bush behind which we must not look; if even then there shall be secret things which belong only to GOD, and which we must not pry into; how much more so here and now! How necessary to remember that we are to know only in part; that we are not to seek to be wise above what is written; that, respecting mysteries which concern not us, it is distinctly charged: “Draw not nigh hither”!
