What feature of creation causes you the greatest wonder, the deepest awe, at the power and wisdom of God? Perhaps that impressive range of mountains near you, or the flitter of a butterfly, or the intricacy of the human eye. The possibilities are nearly endless.
You know the verses that talk about creation as the evidence of God’s hand.
Just a note: the world calls it “nature,” but Scripture never calls creation that. What exists is not merely what is (nature), but what God spoke into being (creation).
