I agree totally; the problem is two-fold;

#1 The rejection of this scripture is usually done by disciples of one who, although vagely understands the identity teaches the common usage of the triune language. So, converting one to the understanding of His deity is difficult.

#2 The revelation only comes to one who wants it. Isaiah 6 "You'll make them see but they will not percieve, hear, but not understand" When you really fall in love with Jesus, you want to know Him, so you hunger for Him.
