There are a variety of ways that people know God. Some people actually don’t know Him at all because they are unconverted and unsaved. But then there are those who know Him casually. They have more of an acquaintance type of relationship with Him. Still other people know God informationally. They can talk about Him fairly regularly and espouse their knowledge of Him. Then there are others who know Him spiritually. They can tell you how it feels when the Holy Spirit moves around or in them.
We are all familiar with the adage: The mind is a terrible thing to waste.

Working with the gift that the brain affords us as human beings grants us a unique and special ability to comprehend.
