In the beginning God created the heavens and the earth. That is how the Bible begins. Immediately you are brought face to face with the fact that God exists. What's interesting is that nowhere in the opening chapter of Genesis does God give us any arguments to try to prove to us that God exists. He doesn't try to convince us based on logic. He simply says, “In the beginning God,” leaving the reader with just two options. You either believe it or you don't.
There are many logical arguments for God’s existence, like the argument of design that says if there is a design, there must be a designer. But logic alone cannot lead you into a relationship with God. A relationship with God must be based on the foundation of faith. That’s what the writer of Hebrews said when he wrote, “By faith -- not by logic, not by science -- by faith we understand that the worlds were prepared by the Word of God so that what is seen was not made out of things which are visible. Faith becomes essential because if you cannot believe by faith that God created the world, how will you ever come to the point where you can believe by faith that Jesus died for your sins and rose from the dead?
