This sermon concludes a set of annual sermons we refer to as our New Year Essentials. These sermons address subjects and important themes that we must repeatedly return to for the glory of God and the transformation of our inner and outer lives. These are not, of course, the same sermons. Rather, they are different sermons, taking different angles, on issues we need to come back to again-and-again. Today, in Isaiah 40:12-26, we consider God's glory as the fuel for God's mission.
