Earthly treasures decay and are vulnerable to be stolen. Men expend great effort and invest large sums to protect their earthly possessions, but they cannot guarantee their security. And ultimately, they must leave them behind. When we serve God, our reward of Heavenly treasure is locked up, as it were, in an impregnable fortress, and it will never decay nor fade.
And we pray:
Fix our thoughts, O God, on the pursuit of holiness, of your Kingdom, and of your glory. And in so far as we labor for treasures, let it be for Heavenly, eternal treasures; not for earthly, temporary things. Let us use the things of this world as we need and in Your service, but let our whole purpose be directed to things above; Amen.
