Do you know that God has a purpose for each one of us? How to know and to achieve it?
"The meaning of your life is much bigger than the satisfaction of personal needs, peace of mind and even your own happiness. It is far greater and more of your family, career, and even the most fantastic dreams and ambitions that you cherish. If you want to know for what purpose you were born on this planet, you should start with God. You were born by His purpose and for the fulfilment of His destination" (Rick Warren, The Purpose Driven Life).
"I therefore so run, not as uncertainly; so fight I, not as one that beateth the air… " (1 Corinthians 9:26)
