"As he neared Damascus on his journey, suddenly a light from heaven flashed around him." Acts 9:3
For Moses, it was the burning bush.
For Peter, it was walking on water.
For Shadrach, Meshach, and Abednego, it was walking through the burning furnace untouched.
For Paul, it was being blinded and spoken to by Jesus on the Damascus road. For Daniel, it was deliverance from the lions' den. For Joshua, it was parting the Jordan River and crossing into the Promised Land. There have been many defining moments in the lives of human beings that changed their lives forever. These defining moments often set the course for the balance of their lives.
We could go on and on. Each of these servants had years of preparation leading up to their defining moment. These moments forced the servants to be involved in something beyond their human experiences. It took them outside their own paradigms of life. God had to move them outside their own boxes. And when He did, their lives were never the same.
You may be in one of three stages of life: You may not have had your "defining moment" yet - God may be preparing you with many important life experiences. You may have had your defining moment and you are living out your call. Or, you may be toward the end of your journey and you have already experienced what I speak of. We are all called to a relationship with God; and we are all called vocationally, which is often ushered in by a defining moment. And there can be more than one defining moment, each pointing you down a path that God foreordained from the foundation of the world. The secret of a great life is often a man's ability to discern the defining moments given to him, understanding them, and learning to walk in the path that leads him to his ultimate destination.
Once you have had a defining moment, you are never the same. Pray that you have eyes to see and ears to hear when your Master brings a defining moment into your life.
