Hosea put it well:
I’ll call nobodies and make them somebodies;
I’ll call the unloved and make them beloved.
In the place where they yelled out, “You’re nobody!”
they’re calling you “God’s living children.”

Isaiah maintained this same emphasis:
If each grain of sand on the seashore were numbered
and the sum labeled “chosen of God,”
They’d be numbers still, not names;
salvation comes by personal selection.
God doesn’t count us; he calls us by name.
Arithmetic is not his focus. 

(Romans 9:25–28, MSG)
