There's one more reason worship should really matter to you--whatever you worship, you become. You can worship whatever you want, but there'll always be a last twist to the story. Whatever you worship, you become obsessed with. Whatever you become obsessed with, you imitate. And whatever you imitate, you become. In other words, whatever you value most will ultimately determine who you are.
If you worship money, you 'll become greedy at the core of your heart. If you worship some sinful habit, that same sin will grip your soul and poison your character to death. If you worship stuff, your life will become material, void of eternal significance. If you give all your praise to the god of you, you'll become a disappointing little god both to yourself and to all those who trust in you.
