God does not require that we do penance on our path back to Him; we can enjoy the things of the world. The problem is that many people become attached to things in the world, whether that be material goods, position, career, wealth, relationships, etc. When you become attached to something, you are putting it above God. He is all that you should be attached to. Remember, everything that happens to you in this world is part of a dream that will fade away. How can you be attached to something that is temporary and will be gone in an instant? Only He is Real. Only He is eternal. Only your relationship as His Beloved is Real. Only your relationship as His Beloved is eternal.
