I've heard people share their life stories about coming to know God many times. They usually make the distinction between knowing about God and personally knowing Him.

I recently heard a young woman from Switzerland share this during a class I taught in a DTS course with YWAM-Jax. I was so encouraged as she told her story with such freshness and sincerity.

So, what is the difference between knowing about God and knowing Him in a personal way?
