The knowledge of God is greater than what man can imagine. We cannot understand God with our human reasoning. The Bible contains the studies and stories about the manifestation of God's power. God has not given the interpretation of His word unto mortal man. He is not what we can understand using our mind and our hearts. Let us not compare the word of God to our mental head knowledge. We should not use science and philosophy to interpret God. God cannot be understood by using our school knowledge.
When we look into the Word of God we can understand that God chooses the foolish things of this world to manifest his glory and power. God does not share his glory with anyone. He has not been sharing his glory with anyone. He will not share his glory with any man. So, God uses those that man does not think that they can do it to perform his purpose on earth. So, human calculation cannot understand what God's way is.
We need the help of the Holy Spirit to understand the Bible. The Bible was written by the Holy Spirit himself. So, we need only the help of the Holy Spirit to understand the Bible. We must allow the Holy Spirit to teach us the Word of God.
