Colossians 3:5

So put to death and deprive of power the evil longings of your earthly body (with its sensual, self-centered instincts) immorality, impurity, sinful passion, evil desire, and greed, which is idolatry (because it replaces your devotion to God).

The things of this world will never satisfy as much as a relationship with Jesus and the Holy Spirit. If we are self-centered, we will never be satisfied and will constantly be looking to fill a void. Jesus came to save us from our sinful nature, evil desires, and greed. Without Jesus providing a way to escape, we would be trapped in them, with no way out.
