Let's Keep It Simple

It seems simple enough that we are assimilated and joined together into and around the Bible as Christians.  However, the way we understand the Bible and view the main theme of the Bible will have drastic results in our assimilation.  For example, if we approach the Old Testament primarily as a collection of stories to make us more moral, we are severely missing the whole point of the Old Testament and being assimilated into a faulty foundation.  Or, if we approach the New Testament primarily as a collection of prophecies predicting the end of the age, we are severely missing the whole point of the New Testament and not being assimilated into the main theme and teaching of the Bible.  
So, what is the main theme of the Bible?  In the story of Jesus dialoguing with two individuals on the road to Emmaus in Luke 24:27 it says, "beginning with Moses and all the Prophets, he interpreted to them in all the Scriptures the things concerning himself."  As we can see, Jesus interpreted the scriptures to the two individuals by showing them that the Old Testament was all about Him.  What this means for us is that our interpretive lens for the Old Testament is simply... Christ. 
As we look to the Gospels of Matthew, Mark, Luke and John... we see four books that are essentially the biographies of Jesus Christ.  Then as we travel to the epistles (i.e. Paul's letters to churches) we see that Paul talks to the churches about Jesus.  Like the Old Testament, the New Testament scriptures are also about Christ.   
So, "just what is the main theme of the Bible?"  We can simply answer this saying, "the whole Bible is a book about.... Jesus!"   What theme and message do we assimilate into?  “We assimilate into the simplicity of Jesus!”
