Relationship with God?

Above: Juarez!  From a lookout point.

I guess it's kind of obvious that I really like the sky.  So here's another sky picture, taken in the morning before one of my runs.  

This morning I woke up at 6:30.  (Now, don't assume I'm one of those structured people that wakes up every single morning at dawn to go through a ritual of exercise and whatever else those people do.  No way).

Our class this morning focused on what being a Christian means.  I feel like every class so far has been like a wave of information that makes me think and process.  But that's good.  It means I'm not wasting my time; it means I'm really taking it all in.  
 

So maybe you want to know what they actually tell us about what it means to be a Christian. May I explain it in terms of how the information has affected me personally, rather than just give a pat answer?
 

You might have heard the term, "having a relationship with God."  And to be honest, for me, being a Christian has come to mean that.  Before, it meant, "to believe a certain set of beliefs." Now, to be more specific, it means "being made acceptable to God through Christ's sacrifice." See, if I have been made acceptable to God, then I can freely relate with him, as a friend.  And, therefore, I have a relationship with God.  

But.  I also don't like throwing around a bunch of terms without defining them, because then the full meaning of what I want to say isn't expressed.  So.  Here are some questions: Who is God, really?  And, why would I want to have a relationship with him?  Man, these are loaded questions that I don't know how to answer.  But what I do know is this: that God has integrity. That I can trust him.  And that deep inside of me, is a desire to be known.
  

I would hate for the term "relationship with God," to be passed over because it's been said so many times.  That's why I ask:  Who is God?  What does relationship with him mean? Meanings can get lost in words because we think we know what something really means.  

My personal experience has taught me that God is worth knowing.  And until I'm not walking on this earth anymore, I'm going to keep pursuing relationship with him.
