“‘You yourselves have seen what I did to Egypt and how I lifted you on eagles’ wings and brought you to myself. And now, if you will diligently listen to me and keep my covenant, then you will be my special possession out of all the nations, for all the earth is mine, and you will be to me a kingdom of priests and a holy nation.’ These are the words that you will speak to the Israelites.”
The if-then statement defines the conditions of being God’s special people. Keeping the covenant meant obeying God’s commandments. Since all the earth is God’s, he chose Israel to represent him in the world.
This condition continues to hold true for the church, which is God’s people today representing his kingdom in the world. Recall a New Testament text about obedience and its place in God’s plan today.
