The newborn Christian finds himself alive with a sweet, enjoyable kind of life that he accepts naively, almost unconsciously. To him everything is simple and immediate. He knows no intermediary. Christ is to him on an infinitely higher level what its mother is to a baby--warmth, nourishment, protection, rest and an object of satisfying affection. Right here is where the wrong kind of Bible teacher can do his damage. The first thing he does is to destroy the new Christian's simplicity. He introduces something between the Christian and Christ. He makes him Biblo-centric instead of Christo-centric. (And there is a difference, let no one deceive you.) The Spirit-anointed Bible teacher will so teach the Word as to keep it transparent, so as to allow it to be what it always should be, a kind of burning bush which God indwells and out of which He shines in awesome splendor. The beholder sees the bush, it is true, but the object of his interest is the Presence, not the bush. The wrong kind of teacher gets so technical about the bush that the fire dims down and the light ceases to fall on the Christian's face.
That is what the gentle cynic meant when he said "before he has met too many Bible teachers."
As for "too many church members" spoiling the new Christian's happiness, it is the result of disillusionment pure and simple.
