Spurgeon, from Counsel For Christian Workers:
Grace does not make us unearthly, though it makes us unworldly.
True religion distinguishes us from others, even as our Lord Jesus was separate from sinners, but it does not shut us up or hedge us round about as if we were too good or too tender for the rough usage of everyday life.
It does not put us in the saltbox and shut the lid down, but it casts us in among our fellowmen for their good.
