The matter of origins … is absolutely critical to all human thinking. It becomes critical to how we conduct our lives as human beings. Without an understanding of origins, without a right understanding of origins, there is no way to comprehend ourselves. There is no way to understand humanity, as to the purpose of our existence, and as to our destiny. If we cannot believe what Genesis says about origins, we are lost as to our purpose and our destiny. Whether this world and its life as we know it evolved by chance, without a cause, or was created by God, has immense comprehensive implications for all of human life.
