There is a tendency, even and maybe especially for us, that we would start to find confidence in what we do or how things are going for us. We’re Christians; that’s why! God knew that this tendency and temptation existed for his people, the Israelites too. He knew that they might (even would) become self-confident. So, God reminded them: “Its not because of you! Its not because of your righteousness, or your size, or anything about you. Its because of me! I loved you. I am doing and giving this to you. And I have set you here so that you might live as my people in this world.”
Here are the two words for Christian life: Loved and Sent. Notice the passive. This is not something we do. It is something done to us and for us. God chooses to love us. God, then, in mercy sends us as his loved children into the world. Deuteronomy 7:7-11
