Some people think the Bible is a book of super secret knowledge, a mystery such as in the book The DaVinci Code. Well, the Bible itself does say it is a mystery! But instead of some secret society type of mystery, the Bible says that God's wisdom can be a mystery. God's wisdom and His plan for humanity have been hard for people to see since the very beginning, even though it is actually in plain sight! This passage lays out how you can see the truth of God, and all it takes is a bit of willingness.
