There are at least two possible reactions to this. First, I can just throw up my hands and give up in despair. After all there is no way I will ever get to know Him completely, it is futile, so why try? The other is to accept what Christ promised in John 16:13 that we will be led in this process into all truth.
The mind blowing thing is that He has chosen to reveal Himself at any level and that He leads us through the process.
