The purpose of life is to realise that the fullness of God is within you and His abundance is at your disposal through His Grace. However, no matter how hard you try, you can never attain to this realisation while you have a selfish disposition simply because your "little SELFishness cannot contain the Almighty. You have to be ready to relinquish your attachment to all the "labels" that identify you in life and open yourself up for the will of God. That means nail your ego to your own cross following the example of Jesus Christ. There you have it. Make your choice.
