God gives them the 10 commandments – basic rules for society to function, and the basis for all western law and civilization. A society ignores these commands to her own fall.
What is so amazing about these rules is how ahead of their time they are – these rules applied to everyone – king and slave, rich and poor, native born and immigrant – no one was higher than God’s law. Pharaoh could change the laws or make new ones – he was the law. We hail the Magna Carta as a monumental moment in human history (and it is) – since it elevates the people and puts them more on level with the nobility and king. This had already happened thousands of years before – on Mount Sinai, with God’s commands.
God is working to grow us as humans. He starts by being all about PROMISES – with Abraham, Isaac, and Jacob. He is now showing them that He is the Deliverer, and He is HOLY – we need to have an honoring fear of God. This grows into a reverent love – knowing who He is, and knowing His love drives out fear. God has not changed, but we have grown in our knowledge of Him, and hopefully closer to Him, too!
