God makes unlikely choices to do His work. God can use you. And me. I’ve often thought that the thing that separates the saints from the rest of us is that when God asked them to do the hard thing, the saints said “yes.” Of course, there is that other thing. The saints knew their righteousness is as filthy rags. God has no use for the ambitious. He has no use for the self-righteous. He has no use for the proud.
God uses us in the broken places. He always begins with unlikely elements. Sometimes, He begins spit and dirt.
