That image of us living behind a horseshoe waterfall, and dwelling in an enormous bejeweled cave with God. Then we turn and look outwards through the water crest and offer things to others. To switch metaphors, we have to live up the mountain, and if we chose, we go down into the valley. But we are not valley folk. We are mountain people, and we need to not define ourselves in the terms of the valley. Jesus lives often in the Valley as well, so we go with Him there, and stay close to Him there. But we have to take care not to assume we are “of” the valley. Heaven is His throne the earth His footstool.
Going back to the waterfall metaphor—we see when we poke our swords through the cascade, that it touches others, and we may get arrows hurled back at us, then we return to the inner cave, but we need not stay there, for Jesus is able to heal quickly. And if we wish to serve others with Him, we may return to the cascade, and the place of interface with the world. And return. When we stick our sword out and interface with the world, we are still protected by the waterfall, yet we make ourself wet with the world.
Some of us have not known the cave well enough, and need to dwell there for a season. These have spent their lives on the crest of the falls trying to help others, but cannot draw from the strength of the inner cave with The Father. Others have only been in the cave, and need to come out and serve others to know of Jesus great labor for the world. To swivel their desk chairs around from the cave and at least consider the crashing of the falls. And the potential glory outside them. The cries and needs coming from the world.
Some parts of the church have known the cave only, or the outer cascade only, and need knowledge of God from the other aspects He would offer us.
