That is like the question, if God is all powerful why can he not create a rock so big he cannot lift it? First of all God is the master creator. He designs and creates the way he chooses. Even if he told us we most likely would not have the intellect to understand everything. However, he has told us enough for us to know him, to find him, to follow him, and for him to live in us through the Holy Spirit. The wisdom of man will never lead anyone to the truth of God and in fact is contra to him because of it's selfish and arrogant attitude and motives. God wants us to honor him for who He is and to love him because He sent his Son to save us and die for us and he wants us to love everyone else as we love ourselves. He wants us to live as servants of others with a purpose of giving not getting. If everyone did that what a wonderful world we would have. But the world is evil and controlled by Satan. Yet by our faith in Jesus Christ we overcome the world.
