This is always the biblical order. God acts first for us, and his action, if properly understood by us, calls for a response of gratitude and thanksgiving.
And God takes it even further. He does not only decide that never again will he curse the ground will flood, but he pledges that to Noah (and to all humanity) through a covenant. And God hangs his "war bow" (rainbow) in the sky, upside down, so it will never be facing the earth. This covenant, a covenant of grace, prefigures the fulfillment of God's covenant of grace in Christ. Here, with Noah, God promises to never destroy the earth again with water. But later, with Christ, God promises to save the world with blood. And the means by which we appropriate this covenant is with water (baptism; 1 Peter 3:21).
God's covenant with Noah was to not destroy; but in Christ, God perfects this covenant beyond not destroying in order to deliver salvation.
