Luther’s THE SMALL CATECHISM divides the Apostle’s Creed into three articles, one for each Person of the Trinity. Here is Luther’s explanation of what it means that God the Father is our Creator:
THE FIRST ARTICLE
I believe in God the Father Almighty, Maker of heaven and earth.
What does this mean?
I believe that God has made me and all creatures; that He has given me my body and soul, eyes, ears and all my members, my reason and all my senses, and still preserves them; that He richly and daily provides me with food and clothing, home and family, property and goods, and all that I need to support this body and life; that He protects me from all danger, guards and keeps me from all evil; and all this purely out of fatherly, divine goodness and mercy, without any merit or worthiness in me; for all which I am in duty bound to thank and praise, to serve and obey Him. This is most certainly true.
Notice that the Father Almighty as Creator means more than what He did long ago in Genesis. He preserves our existence; He “daily” gives us our sustenance, our material goods, and our family; He protects us; He extends His grace.
