theme of your life so far.

I think the theme of my life so far is still being written, how does anyone know the theme of there life, if they are still living? God created the heavens, earths, angels, humans, beasts and etc. Understanding creation the animals all have purpose even the plants and the angels; however, the complexity of humans some they don't understand why they here and purpose of creation. Being that I'm still a living vessel the theme of my life so far would be finding my true purpose for living and understand myself as creation of the most high.
