The Treasures of Wisdom and Knowledge

All those evil doctrines about God that work misery and madness, have their origin in the brains of the wise and prudent, not in the hearts of the children.
— George MacDonald, The Yoke of Jesus, The Hope of the Gospel

Matthew 11:25 (NIV)
At that time Jesus said, “I praise you, Father, Lord of heaven and earth, because you have hidden these things from the wise and learned, and revealed them to little children."

Matthew 18:3-4 (NIV)
3 And he said: “Truly I tell you, unless you change and become like little children, you will never enter the kingdom of heaven. 4 Therefore, whoever takes the lowly position of this child is the greatest in the kingdom of heaven."

1 Timothy 4:1 (KJV)
Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils

1 Corinthians 1:27 (New American Standard Bible)
...but God has chosen the foolish things of the world to shame the wise, and God has chosen the weak things of the world to shame the things which are strong

So, you may ask what about the wisdom literature in the Bible--especially in the book of Proverbs where wisdom is personified as more precious than jewels and blessed is the person who finds wisdom? There is a big difference in man's wisdom and God's wisdom. There is a way that seems right to a man, but it's end is the way to death (Proverbs 14:12). God's thoughts are higher than our thoughts.

Romans 11:33-34 (NIV)
Oh, the depth of the riches of the wisdom and knowledge of God!
    How unsearchable his judgments,
    and his paths beyond tracing out!
“Who has known the mind of the Lord?
    Or who has been his counselor?”

How can men with finite minds truly grasp an infinite God? It is more important to obey Him than try to understand Him. And knowing Him personally is different than knowing about Him. We have to become like children to depend on our Father for everything. We can depend on ourselves no longer. We have to be born again. 

John 3:1-15 (ESV)
Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews. 2 This man came to Jesus by night and said to him, “Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do unless God is with him.” 3 Jesus answered him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.”4 Nicodemus said to him, “How can a man be born when he is old? Can he enter a second time into his mother's womb and be born?”5 Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. 6 That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. 7 Do not marvel that I said to you, ‘You must be born again.’ 8 The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit.”

9 Nicodemus said to him, “How can these things be?” 10 Jesus answered him, “Are you the teacher of Israel and yet you do not understand these things? 11 Truly, truly, I say to you, we speak of what we know, and bear witness to what we have seen, but you do not receive our testimony. 12 If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things? 13 No one has ascended into heaven except he who descended from heaven, the Son of Man. 14 And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, 15 that whoever believes in him may have eternal life. 

It is in Christ, "in whom are hidden all the treasures of wisdom and knowledge." Colossians 2:3 (NIV)
