This does not mean that I cannot desire to be blessed by my service to God. In fact, God promises to bless our obedience according to His loving purposes, and in some measure He uses these blessings to encourage us to honor His standards. The point is not that His blessings should never motivate us at all, but they cannot be the driving force of our service. His blessings are the oil that helps the machinery of obedience operate, but love for God and desire for His glory are the pistons and wheels.
