"The LORD did not set his affection on you and choose you because you were more numerous than other peoples, for you were the fewest of all peoples. But it was because the LORD loved you and kept the oath he swore to your ancestors that he brought you out with a mighty hand and redeemed you from the land of slavery ..." (v 7-8).Today we seem to have two opposing self-esteem problems — both in our society at large and in the church. On the one hand we have people who think they are the lowest of the low, the stuff dirt looks down on. Maybe it's due to things in their past, or maybe it's just how they see themselves. These people cannot imagine they have any value and can't believe God could want them.
On the other hand we have people who think they are so fabulous that the stars themselves need to wear shades to look upon them. Their egos tend to be a little fragile, but they want to think they are reason the sun rises in the morning. And they seem to think God is lucky to have them.
God's message to his chosen people, to the nation he was giving "a land flowing with milk and honey," was that they were nothing special. "I didn't rescue you because you were so wonderful. I just loved you."
God's message to his redeemed people, to the nation he gave his Son for, is that we are nothing special, but he loves us: "Brothers and sisters, think of what you were when you were called. Not many of you were wise by human standards; not many were influential; not many were of noble birth. But God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong" (1Cor 1:26-27).
God takes things that aren't special and makes them special. He takes ashes and makes crowns, slaves and makes sons. God doesn't want anyone who thinks they're special. But he collects the worthless and counts himself richer because of them.
