Reading the Bible Through

Leviticus 3 - 7   What are all these offerings? I guess I need to learn what they mean and/or symbolize. As I am listening to these chapters, I notice that one place says the person "must confess." It reminds me that confession can feel so shameful, but can be so empowering. I am reminded of the work of Brene Brown on shame. She reports that shame grows with secrecy, silence and judgement, but is mitigated with empathy.  I have been told that we, as Christians, no longer need to make animal sacrifices because Jesus fulfilled that requirement by dying on the cross for us. I do believe that, but still I don't understand the meanings and symbolisms behind all of these different kinds of offerings. Also, we may still give offerings and/or tithes of our money. Wasn't their animals entwined with money/financial status in the days this was written? 

Exodus 40 - Leviticus 2   The cloud and fire of the Lord was in sight of the Israelites and guided all their travels. May I follow God so completely.  "The salt of the covenant  of your God" This is a new phrasing. What is the significance of salt? It gives flavor, but what is the whole  meaning here in this passage?  Most of the time, I find Leviticus fairly boring. However, one time, it really spoke to me of the holiness of God. We shall see how I find it in this reading currently.
