Sparky - You've brought out a very important point..
Many people don't understand the apparent differences between the Character of Jesus, and that of Jehovah..
Jehovah is portrayed as a hateful, "jealous", war Mongering God, that loved 1,000's of animals to be sacrificed to him.
If you really examine the OT as you have done, you will see Two Narratives.
1. Narrative 1 - Jehovah who is Love, and expects nothing other than following his Simple Laws that are in place for the betterment of Humanity.
2. Narrative 2 - Man made Laws,Traditions and Rituals which were later further distorted by Creeds & Organizations changing the Bible to suit their agendas.
An example of this is seen in Animal Sacrifice.. As we know it is scattered all through out The Old Testament. They are said to be "A restful odor to Jehovah" however compare this to what Jehovah says through his True Prophets - Judge for your selves, if the below words speak of a God that demands Animal Sacrifice, or even Enjoys the death of innocent animals.
