Pastor and author Rick Warren, became famous (and rich) when he wrote his best seller "Purpose Driven Life." He came back and wrote another book that was even more successful "The Purpose Driven Church."
The reason for the popularity is two-fold. First, deep down within, everyone wants to know their purpose. Second, most people don't know how to discover their purpose. While I am grateful for the gift God gave to Pastor Warren (I enjoyed and taught from both books), the truth is, that the only way to know our purpose is studying the Word of God. Attendance in Sunday school and Bible study, combined with personal, daily devotion and prayer will not only help us to discover our purpose, but also develop our purpose.
It's sad to say that people wonder through life aimlessly because they do not know their purpose. Do You?
