Exodus 24 Covenant

Part 1 - Consequence and Covering
What was up with Moses collecting the blood from the animal sacrifice? (which was not killing an animal to please God, but instead an appropriation of the butcher shop for a religious purpose)

Part 2 - Chosen
God does the work, and we agree to follow.  
God has established His witness and testimony among us, and we decide to follow.  
God brings us to where we may agree sincerely, and then we are accountable.

Part 3 - Commitment
Do you live your life like a person who is committed to Jesus.  
Would it mean more if we had been speckled with the blood of an animal sacrifice? 
Or if you had signed on the dotted line?  
What is the basis of our belief and behaviour?
