Ex nihilo is Latin for “from nothing.” The term creatio ex nihilo refers to God creating everything from nothing. In the beginning, God created the heavens and the earth (Genesis 1:1). Prior to that moment, there was nothing. God didn’t make the universe from preexisting building blocks. He started from scratch.
These first two verses are an introduction to the story of creation. Who is God? He is Elohim, the Creator. There is an understood connection to the God, the nation of Israel already knew as their Redeemer and Protector.
The Beginning is our origin point, but not God’s. He existed before the universe, before we had the measurement of time, before anything.
God as all-powerful creator, who was and is and is to come, is our ultimate authority. He is the one we answer to. His Word, the Bible, is His story including how we can know Him and have a relationship with Him.
