Against overwhelming odds, and practically at the brink of extinction, King Alfred beat back the invasion of the pagan Danes and, for all practical purposes, founded the nation that would be known as England. And by God’s sovereign grace, within a single generation or two, the pagan invaders who stayed were Christians, too.
But if the Lord is for us, then who can be against us? (Romans 8:31)
