spiritual comprehension between adult and childlike understanding can be simply understood as the child staying in his comfortable world of english and math. no alternative abberations or interralated interpretations for the child like mind. only simple comprehension of clearly stated fact. while adult comprehension is everflowing alternating recogitive interpretation. that moves like the wind. daves uses of symbols are given to him in two ways. first he knows his bible. its definition of symbols and use of language. second the revelations in understanding he receives must align themselves like two lites creating one shining beacon. they witness together as one absolute truth. "out of the mouth of two or three witnesses let every word be established"..dave knows his bible and verifies his revealtions received using his own gift of tounges in every song. the spiritual truth is there. its his work. only most people overlook the symbols interwoven within. but thats also the will of God. everything in its own season... is God playing a trick on the audience through Dave.. does spock have pointy ears..you bet! further insight to the bibles symbolic definition search the web for "dayspring from on high" at kingdomlife.
