Does the Bible give any reason as to why its content is sometimes difficult to interpret? As evidenced by this site, and the divisions between various Christian denominations, there seems to be a lot of different ways some passages in the bible can be interpreted.

One example is Chronicles 16:30: "Tremble before him, all the earth!  The world is firmly established; it cannot be moved." For hundreds of years (and still some today) some Christians interpreted this to mean the earth is the center universe and does not move.

So is there anything in the Bible that clearly states why some passages are written in such a way as to potentiate interpretation? 

If not, is there anything in the Bible that may even suggest or hint at why this is, or perhaps a story alluding to this like someone navigating a task though directed by unclear instructions?
Yes, absolutely
First understand these premises, earthly wisdom and Godly wisdom.

James 3:14-15  (NIV)
14 But if you harbor bitter envy and selfish ambition in your hearts,
do not boast about it or deny the truth. 15 Such “wisdom” does not
come down from heaven but is earthly, unspiritual, demonic.
James 3:17 (NIV)
17 But the wisdom that comes from heaven is first of all pure; then
peace-loving, considerate, submissive, full of mercy and good fruit,
impartial and sincere.

Isaiah was commissioned by God to go and rebuke a wicked people and deliver this curse to them.

Isaiah 6:9-10 NIV
9 He said, “Go and tell this people:
“‘Be ever hearing, but never understanding; be ever seeing, but
never perceiving.’  10 Make the heart of this people calloused;
make their ears dull and close their eyes. Otherwise they
might see with their eyes, hear with their ears, understand
with their hearts, and turn and be healed.”

Wicked people and the wisdom of this world
God has purposely shut off the understanding of His word to the common man. Because of that mans wickedness he will never know the truth about God. But if that man turns from his wickedness, repents, and has faith in Jesus Christ, then God will open the flood gates of wisdom so that you may understand His word.

Ephesians 4:18
They are darkened in their understanding and separated from the life
of God because of the ignorance that is in them due to the hardening
of their hearts.

Children of God
