While there is much in the world to love, it is best loved in relation to the One who made it. The world is beautiful, but much fairer is the One who fashioned it. The world is glorious, but more delightful is the One by whom the world was established. Therefore, let us labor as much as we can, beloved, that love of the world as such may not overwhelm us, and that we may not love the creature more than the creator. God has given us earthly possession in order that we may love him with our whole heart and soul. But sometimes we provoke God’s displeasure against us when we love his gifts more than God himself. The same thing happens in human relationships. Suppose someone gives a special gift to his protégé. But the protégé then begins to despise the giver, and loves the gift more than the one who gave. Suppose he comes to think of the giver no longer as friend but enemy. Just so it is with our relationship with God. We love more those who love us for ourselves rather than our gifts. So God is known to love those who love him more than the earthly gifts he gives.
