This verse explains what is happening today in the post-modern church teachings that are blinding the ones who desire Truth. This explains the fact some people say "I didn't get anything from church today" when they leave church on Sunday. If it did not tickle their ears they are not for it. If it offends they leave or get angry. This is because God is not in them, and they do not seek Him. They prefer the words of man over the Word of God.
