Loving God is the most important thing. Just like being in the sun is the most important thing for a sunflower. When you love God it is like when a sunflower reflects sunlight back towards the sun. The sunflower could not possibly hope to reflect back as much sunlight as it gets. But it reflects what it can. That reflected sunlight is not exactly what makes or breaks the sun.
To deny God is for a sunflower to hide from the sun. Facing the sun all day long is what is best for the sunflower. That is how it can do all the sunflower things it might want to do. Love of God has to be the central organizing principle for all humanity.
