Is It True That God Knows More about us than we know about Him?

       Is It True that God knows more about us than we know about Him?  The reason why I am asking this question is because I got into an argument with a close friend because she stated that she knew me more than God and my own mother.  I really do not understand why she stated it in the first place.  I know that according to Isaiah 55:10; it says that our ways are not His ways and our thoughts are not His thoughts. 

       Next, I did not mean to make my friend mad at me, but she does not know me in the same way that God knows me.  I had to apologize to her because I explained to her that God’s ways and thoughts are not our thoughts.  I only want to ask this question because it is impossible for a human being to know us like God.  I am only saying that God sees the heart. 

I want to say that human behavior is learned.  I know that all behaviors are learned and imitated.  I am a person who understands the Holy Bible.  I try my best to abide by the Bible.  I want to ask this question because people do not know us in the same way that God knows us.  Is this true that a human being knows me more than God?  Please help me to clarify this matter.
