"Get thee hence and turn thee eastward, and hide thyself by the brook Cherith" (1 Kings 17:3). The man who is to take a high place before his fellows must take a low place before his God, and there is no better manner of bringing a man down than by suddenly dropping him out of a sphere to which he was beginning to think himself essential, teaching him that he is not at all necessary to God's plan, and compelling him to consider in the sequestered vale of some Cherith how mixed are his motives, and how insignificant his strength.
Elijah and the Secret of His Power - Chapter 2, by F.B. Meyer
So the Master dealt with His apostles. When, on one occasion, they returned to Him, full of themselves and flushed with success, He quietly said, "Come ye yourselves apart into a desert place." We are too strong, too full of self, for God to use us. We vainly imagine that we are something, and that God cannot dispense with us. How urgently we need that God should bury our self- centeredness in the darkness of a Cherith or a tomb, so as to hide it, and keep it in the place of death. We must not be surprised, then, if sometimes our Father says: "There, child, you have had enough of this hurry, and publicity, and excitement; go and hide yourself by the brook -- hide yourself in the Cherith of the sick chamber, or in the Cherith of bereavement, or in some solitude from which the crowds have ebbed away." Happy is he who can reply, "This Your will is also mine; I flee to You to hide me. Hide me in the secret of Your tabernacle, and beneath the cover of Your wings!"
Every saintly soul that would wield great power with men must win it in some hidden Cherith. A Carmel triumph always presupposes a Cherith; and a Cherith always leads to a Carmel. We cannot give out unless we have previously taken in. We cannot exorcise the devils unless we have first entered into our closets and shut our doors and spent hours of rapt intercourse with God. The acquisition of spiritual power is impossible, unless we hide ourselves from men and from ourselves in some deep gorge where we may absorb the power of the eternal God; as vegetation through long ages absorbed these qualities of sunshine which it gives back through burning coal. - F.
