Is it contrary to any Christian belief or doctrine to believe that Jesus deceives us in order to protect our souls? Jesus ultimately cares about the judgement of our eternal soul.

Is it contrary to any Christian belief or doctrine to believe in a Holy deception;  that the reason He made His return unknown and mysterious is to keep us in line or away from sin?   

If we are anxiously awaiting that he can return any moment, we are more likely to stick to His way and in result, preserve our soul?  I am not saying He is lying, but loves us so much that He will give us any impression possible to keep us away from the Devil or Hell.  

Does this go against any other Christian belief or doctrine?

EDIT

Notice how Biblical passages can look like lies but are not. Please read this very good Christian writers article: http://www.christianitytoday.com/ct/2005/october/26.56.html


  "He will rescue you from every trap and protect you from the fatal
  plague. … For he orders his angels to protect you wherever you go.
  They will hold you with their hands to keep you from striking your
  foot on a stone." [All Scripture citations from the New Living
  Translation.]
  
  At first blush it sounds really good, but that day I had to say what I
  really thought. Through tears I told the group, "I don't get how this
  is true. He did not rescue us from a fatal plague. He did not keep us
  from striking our feet on a stone but, in fact, allowed much worse
  than that."
I know I should probably reference these, but I'm going to appeal to common knowledge

Before answering, I just want to re-emphasize two central teachings that are common to the vast majority of Christianity:


It's safe to say that almost every denomination, and almost every major division within Christianity agrees that God does not and cannot lie.  I'm sure there are exceptions to that rule, and agnostics/atheists may balk at the idea, but for the most part that's accepted teaching for the vast majority of Christianity.
Most (but not all) Christian denominations and traditions accept the Diety of Jesus.  In other words, Jesus is God. (There are exceptions.)


If the second point is true, then to say that Jesus lies is to say then God lies.  And the first point flat out denies that.

So, according to Scripture, as understood by the overwhelming majority of Christianity, it is absolutely a heresy to say that Jesus would deceive us to protect our souls.

And most denominations that I am aware of state that Heresy is a sin.  

So yes, to the overwhelming majority of Christianity,  it would be be accurate to say that it's a sin to believe that Jesus would lie to us to protect our souls.  Not only does it go against "any other Christian belief or doctrine" it goes against two central, almost universally held Christian beliefs/doctrines.  The doctrine of God's character and the doctrine of Christ's Diety.
