This is because whereas knowledge grows (and can be easily abused) by probing and experimentation; wisdom (which must be earned) is gained by the application of experience (the former can be fed by immediate gratification, where the latter cannot) and righteousness (which is regulated outside of man, by a Superior Being – God). And when God is separated from either or both, the result in doomed to degradation.
Wisdom is the correct application of knowledge – yet always according to God’s Word.
“Sanctify them through thy truth: thy word is truth.” (John 17:17)
“Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.” (John 14:6)
