Are faith in self and faith in God mutually exclusive?

 To me one of the stark differences between the Old Testament and the New Testament is difference in the interaction with God.   

 
What I mean by that is in the OT it is very much about fear and quaking in your boots.  In the NT it is more about building a relationship with God.   
 
That is why I love what Job says in the passage.   

 

Job 13:15  Though He slay me, yet will I trust Him.  Even so, I will defend my own ways before Him.  

 

In this passage Job is referring to God.  Job has enough faith in God's sense of justice that instead of groveling in fear, Job is saying I'm willing to stand face to face with God and let him decide.  I don't believe I did anything wrong and I am going to defend myself directly to God!  I'm willing to accept God's decision either way. 
 
Wow!  That is some pretty strong faith....in two things.  Faith in self and faith in God. 

 

Wait a minute, aren't those to mutually exclusive? 
 
I don't believe they are.  We are told we are made in the image of God.  Does God seem to be lacking faith in Himself?  Doesn't seem that way to me. 

 

Therefore I would contend that God would expect us to have great faith in ourselves and to exercise that faith in self in God's service.   

 

Here is the caveat.  As long as we keep our faith subservient to God's faith.  Does that make sense?
