A large percentage of the bible is in mysteries, parables, allegories and riddles---so why not the bible codes?
Jesus only spoke to the crowds in riddles/parables:
"And with many such parables spake he the word unto them, as they were able to hear it. But without a parable spake he not unto them: and when they were alone, he expounded all things to his disciples," (Mark 4:33-34).
The purpose of the riddles are to hide His words from the hard-hearted:
"And the disciples came, and said unto him, Why speakest thou unto them in parables? And he answered and said unto them, Unto you it is given to know the mysteries of the kingdom of heaven, but to them it is not given. For whosoever hath, to him shall be
given, and he shall have abundance: but whosoever hath not, from him shall be taken away even that which he hath. Therefore speak I to them in parables; because seeing they see not, and hearing they hear not, neither do they understand. And unto them is fulfilled the prophecy
of Isaiah, which saith, By hearing ye shall hear, and shall in no wise understand; And seeing ye shall see, and shall in no wise perceive: For this people's heart is waxed gross, And their ears are dull of hearing, And their eyes they have closed; Lest haply they should
perceive with their eyes, And hear with their ears, And understand with their heart, And should turn again, And I should heal them. But blessed are your eyes, for they see; and your ears, for they hear. For verily I say unto you, that many prophets and righteous men desired to
see the things which ye see, and saw them not; and to hear the things which ye hear, and heard them not," (Matt. 13:10-17).
I believe that the bible codes are in riddles to fulfill the word of Isaiah the prophet:
"Whom shall He teach knowledge? And whom shall He make to understand doctrine? Those weaned from the milk and drawn from the breasts. For precept must be on precept, precept on precept; line on line, line on line; here a little, there a
little; for with stammering lips and another tongue He will speak to this people. To whom He said, This is the rest; cause the weary to rest; and this is the refreshing. Yet they were not willing to hear. But the word of the LORD was to them precept on precept,
precept on precept; line on line, line on line; here a little, there a little; that they might go, and fall backward, and be broken and snared and taken," (Isaiah 28:9-13).
I do not think that it is a coincidence that the mene-tekel bible code went public 2000 years (of the 360-day calendar) after Pentecost. (Click
here for more details on this statement. The initial fulfillment of the above verse was also at Pentecost of AD 30, cf., Acts 1.)
"In the law it is written, With men of other tongues and other lips will I speak unto this people; and yet for all that will they not hear me, saith the Lord. Wherefore tongues are for a sign, not to them that believe, but to them that believe not: but
prophesying serveth not for them that believe not, but for them which believe." (ICor. 14:21-22).
Therefore, for the bible codes to come in any other mode other than riddles and parables (i.e., 'the symbolic pictures'), would be out of character for the bible, and therefore out of character for God.
You must ponder what the riddles mean! You must decide what the picture-parables are saying! And it is God who weighs your heart. This is why the grand archetype of all the bible-code riddles is the mene-tekel-peres bible-code riddle.
Picture Bible Codes seem incredulous, nevertheless they are real! By so lifting them beyond what man can believe, (because they are too great), He thereby blinds those whose hearts are hard. They are blinded by the light. However, to the broken hearted He
gives grace---to those who know they are blind without Him.
