Rejoice in the Lord always: and again I say, Rejoice.…
To rejoice is in one sense a happiness, in another a duty. In one sense it is an art: there are those who contrive to rejoice, find food for joy, where others can see nothing but gloom and grief: in another aspect it is an attainment; a result arrived at by long experience, in the latter days of a consistent Christian course. But in every point of view Christian joy can only be found in the Lord; by communion with Him, by close watching, by living much in things above. Compromises with the world drive it away. Sin destroys it in a moment.
