"It is the Creator God who is understood to be the redeemer of Israel from Egypt."
I think this understanding is foundational for children and
faith. In my mind, Creation is all that God's hands have made. In my
mind, God as Creator is something concrete!
The author quotes Rolf Rendtorff: "faith in God the Creator was
perceived and experienced as the all-embracing framework, as the
fundamental, all-underlying premise for any talk about God, the world, Israel, and the individual."
"...the underlying premise for any talk about God..." Apply that to working with children.
