We all have a purpose in this life. We all have been blessed with gifts from God. At the fundamental level, we all are assigned with the purpose to love one another and to serve one another.
It is after we properly establish this for ourselves can we then explore our wider purpose. In what ways will you specifically love others? What has God called you to do now that you understand the core idea?
I believe that many are in pursuit to find this God-given purpose, perhaps unknowingly, because it is something that will help our search for fulfilment. Yes, living in fellowship with Christ brings fulfilment alone, but expressing his love to people around you strengthens it (which is perhaps what true fellowship with Christ is already).
Finding your God-given purpose allows you to wake up every day and 'serve with strength', because you are sure of what you are doing and know that it is good.
And finally, whatever you do, it will bring glory to God, for the love you transmit is the love of Christ.
