God didn’t choose the Israelites because there was anything particularly wonderful about them. And He continues to choose people who are no big deal in the eyes of the world. Again, it isn’t about me, it’s about God.
God chose the Israelites because of His love. It’s the same today. We wouldn’t stand a chance without God’s love.
The people are reminded in Deuteronomy of what God has done for them. He rescued them from Pharaoh and a life of slavery. God will take care of Israel’s enemies.
Israel was called as a people, we are called as individuals. They had a group relationship with God, we have an individual relationship.
What is required of God’s ancient people? “God keeps His covenant of loyal love with those who love him and observe His commandments…so keep…the rules and regulations that I command you today.”
What about Christians? What are we to do? An old hymn (1887) says it in a nut shell, “Trust and Obey.” It’s that simple.
