In Mark 4:21, Christ continues to, quite literally, deepen his point about how the word works; by which he also means how He works. He is an idea, like a seed, or a need, deeply hidden, that on purpose hides because hidden things must of themselves, by their very nature of hiddenness, be revealed. The ultimate purpose of hiding a thing is not so it can remain hidden, but so it can be revealed. It is quite obvious that a thing can be disclosed only if it is first closed. And Christ is the great closer of doors so one may finally walk through them. He's the great hider of pearls and coins and treasure so one may finally find them. And Christ seems to say if he hides in mankind--those empty fields marked for a beautiful garden, those second, yet barren, Edens--that is, if the word, like a seed, is planted deeply enough, it will, by its very nature, and to the degree the soil is soft and the planting deep, burst forth with manifold produce and fruition. A thousand golden apple-shaped Kingdoms will grow from the Living Tree of God one becomes. And if the measure one uses is a deep measuring stick, then the height he grows will be all the more; however, if one is shallow ground or hard, measuring Jesus with a shallow stick or no stick at all, almost a zero stick, then the seed will be taken away. And even what one had will be taken away.
Revealed things aren’t hidden, rather hidden things are revealed
