Then Moses went up to God, and the LORD called to him from the mountain and said, “…You yourselves have seen what I did to Egypt, and how I carried you on eagles’ wings and brought you to myself. 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, you will be for me a kingdom of priests and a holy nation.” (Exodus 19:3-6)
“The Lord redeemed his people, delivering them from the Egyptians, bearing them through their journey, bringing them to himself. All of this was rooted in God’s gracious covenant. He remembered his covenant with Abraham (2:23–25). He claimed Israel as his ‘firstborn’ (4: 22). He took Israel as his own people and gave them glorious covenant promises (6:6-7). Therefore he redeemed them out of Egypt, out of the house of slavery (i.e., life maintained by human work).
Now, the Lord will give his redeemed people his requirements (20:1ff), essentially saying, ‘This is what it looks like to live in a blessed relationship with the God who has redeemed you.’ And he will give the promise of redemption’s (not work’s) reward: they will be God’s treasured possession and they will be to God a kingdom of priests and a holy nation.
This movement of God’s grace is the same for God’s people today. God redeems us through Jesus Christ because of his gracious covenant; he gives us the requirements of his Word, picturing the life of grateful obedience; and he declares redemption’s reward, that we would be his inheritance (Eph. 1:18), his treasured possession, a kingdom of priests, and a holy nation (1 Pet. 2:9; Rev. 1:6).” [ESV Gospel Transformation Bible]
Let’s pray: Lord, thank you for Your grace in Jesus Christ. Not only did You rescue us from our sins, but You have saved us for a purpose, to be Your treasured possession, a kingdom of priests, a holy nation in this world. We rejoice in Your redemption plan!
