"Six geese a-laying?" Hmmm. Six days of creation, apparently. Scripture begins with an account of Creation that is incredibly brief and yet theologically rich. The fact that God is Creator and First Imaginer is fundamental to all creative activity. As creatures made in God's image, we image His creative nature. We cannot help but create. It is who we are. The only question is for whom we create. Will our imaginings honor and glorify God or honor ourselves?
A lot of ink has been spilled on the question of whether the six days of creation are 24-hour days or merely long periods of time. Both are defensible positions. However, the big story of these days is that God initiates and superintends the creative process. It is not the product of random forces.
Creation's rootedness in the Trinity is also instructive for our own creative activity. Creation occurred in community, a triune community of love -- Father, Son, and Holy Spirit. To me that implies that our own imaging of this creative activity is not simply self-expression but arises out of community. For Christians, this is the Body of Christ, the Church. There is accountability. We do not create in a void. Creative activity should be encouraged by the Church; artists should be accountable to the Church. There is mutuality.
Finally, God's creative activity builds on itself, like a good story. It reminds me that He is not done yet, that His Kingdom is growing, that He is at work even now re-creating human beings to more reflect His original design for them, that one day his work will be done and He will truly, and finally, rest in what He has made and remade.
