The knowledge of God is higher than the knowledge of man. God wisdom and ideology are foolishness unto the carnal minds. Why is it foolishness to them? It is because man does not reason like God. What God treasures, humans do not value that. The ways of God is absolutely unfathomable to carnal minds. For instance, the wisdom of God says that you will get more and grow richer as you give. But the thinking of man says that the more you keep for yourself, the more you will have. These are two contrary ideologies. What God teaches, the humans cannot understand. So, the Bible is not what the educational knowledge gained through this world's system can understand and explain.
The wisdom of this world is foolishness unto God. It is what has been coming to naught. That is to say that the wisdom of the world tends to emptiness and naughtiness. It is valueless and worthless. So, the knowledge of the world cannot explain the word of God. The Bible is the word of God. Its teachings and precepts are not understood by carnal minds. Having this world education does not make one qualified before God. The highly learned men and women in this world cannot understand what the Bible teaches because what the Bible teaches can only be understood by the Holy Spirit. It is the Holy Spirit alone that can explain the things of God to us.
