On the very first page of Scripture, we encounter an emphatic statement of the biblical worldview, one that presupposes the existence of God as the almighty, omnipotent Creator who has no equals. Genesis 1 tells us as much about God as it does about creation. So when we read “in the beginning God created,” we understand that, contrary to an atheistic worldview, the Bible teaches that God exists. Contrary to other creation narratives outside of the Bible, and contrary to the worldview of our pluralistic age, God existed prior to anything else. He isn't one of many gods. And God isn't engaged in a battle against evil as if He has an equal.
Then God speaks, saying, "Let there be light." Again, this tells us as much about God as it does His creation. God is the one who speaks and creation responds. Creation responds immediately and in exact obedience to His command. God is a powerful God. He is authoritative over all of creation, and He is good. That's why the refrain throughout the first chapter of Genesis is that “God saw that it was good.” In effect, God declares His goodness to the creation that He made.
Towards the end of the chapter, we see how God created humanity as the pinnacle of the created order. And God intends to be in relationship with us. So you see the Bible teaches not only God's existence but His relational presence towards us. Though we don't see God, we experience His kindness in hundreds of different ways every day. His provision, His care, and His providence all testify to His presence. Then, of course, later in redemptive history, we see that God Himself showed up in the form of a man, Jesus Christ.
There really is no way to explain the life, death, and resurrection of Christ without understanding Him as God. Humanity experiences the reality of God's existence in the most personal way through the ministry of Jesus Christ. And it is through faith in Him that we come into a relationship with God, experiencing not just the fact of His existence, but the reality of His redeeming love and restoring purposes. One day the whole earth will acknowledge the truth of God's existence. We can delight in it now through Jesus.
