'A beautiful face is at all times pleasing to the eye, but the especially when there is joy manifested in the countenance. Joy in the face puts a new beauty, and makes that which before was beautiful to be exceedingly beautiful. It puts a lustre and glory upon beauty; so does joy in the face, heart, and life of a Christian, cast a general splendour and glory upon him, and the ways of God wherein he walks.'
Thomas Brooks, Heaven on Earth, p.29.
