Satan replied to the Lord, "Yes, Job fears God, but not without good reason! You have always protected him and his home and his property from harm. You have made him prosperous in everything he does. Look how rich he is! But take away everything he has, and he will surely curse you to your face!" (Job 1:9-11)(NLT)
Satan argued that Job followed God simply because he received blessings for doing so. Take away the rewards and Job would cease to worship God. No doubt Satan intended to direct this accusation toward all people who follow God. A modern pragmatist might state the accusation this way: To the extent that it is in a person's self-interest, that person will honor God. But God knew that Job would maintain his allegiance despite his suffering, for Job considered God worthy of worship simply because he is God. Like Job, let us worship God for who he is rather than for what he gives us.
WORTHY LORD, we praise you for who you are. Purify our motives for following you, and teach us to draw closer to you in the midst of our pain. You alone are worthy of everlasting honor. Amen.
