The types and shadows are to be seen written in the scriptures those who have "eyes to see". Anyone can read the Bible, but not anyone can understand God's message to men written in the Bible.
"For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, 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 have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them." Matt 13:15-16
