3 Then Moses went up to God, and the Lord called to him from the mountain and said, ‘This is what you are to say to the descendants of Jacob and what you are to tell the people of Israel: 4 “You yourselves have seen what I did to Egypt, and how I carried you on eagles’ wings and brought you to myself. 5 Now if you obey me fully and keep my covenant, then out of all nations you will be my treasured possession. Although the whole earth is mine, 6 you will be for me a kingdom of priests and a holy nation.”
The LORD delivers Israel in the Exodus so that they would become the people they were called to be, His People, “a Kingdom of priests and a holy nation”, to enter into a covenant with Him.
Kingdom and Covenant: two key themes in the Biblical Story. Covenant comes from relationship with God as King. The Kingdom creates the Covenant. “The Covenant was a way in which these redeemed people could relate to God and to each other and demonstrate to the world what being the people of God was really like” -Winn Griffin 
Today, what is your relationship with God like?
Read 1 Peter 2:9-12…
But you are the ones chosen by God, chosen for the high calling of priestly work, chosen to be a holy people, God’s instruments to do his work and speak out for him, to tell others of the night-and-day difference he made for you—from nothing to something, from rejected to accepted.
Friends, this world is not your home, so don’t make yourselves cozy in it. Don’t indulge your ego at the expense of your soul. Live an exemplary life among the natives so that your actions will refute their prejudices. Then they’ll be won over to God’s side and be there to join in the celebration when he arrives. (The Message)
How will you show others that you belong to the LORD? How will you proclaim what He has done in your life? How will you live “an exemplary life’?
