These two are not contradictory. These two states of mind, both of them the natural operations of any deep faith, may co-exist and blend into one another, so as that the gladness is sobered, and chastened, and made manly and noble; and that the sorrow is like some thundercloud, all streaked with bars of sunshine, that pierce into its deepest depths. The joy lives in the midst of the sorrow; the sorrow springs from the same root as the gladness. The two do not clash against each other, or reduce the emotion to a neutral indifference, but they blend into one another; just as, in the Arctic regions, deep down beneath the cold snow, with its white desolation and its barren death, you will find the budding of the early spring flowers and the fresh green grass; just as some kinds of fire burn below the water; just as, in the midst of the barren and undrinkable sea, there may be welling up some little fountain of fresh water that comes from a deeper depth than the great ocean around it, and pours its sweet streams along the surface of the salt waste. Gladness, because I love, for love _is_ gladness; gladness, because I trust, for trust _is_ gladness; gladness, because I obey, for obedience is a meat that others know not of, and light comes when we do His will! But sorrow, because still I am wrestling with sin; sorrow, because still I have not perfect fellowship; sorrow, because mine eye, purified by my living with God, sees earth, and sin, and life, and death, and the generations of men, and the darkness beyond, in some measure as God sees them! And yet, the sorrow is surface, and the joy is central; the sorrow springs from circumstance, and the gladness from the essence of the thing;--and therefore the sorrow is transitory, and the gladness is perennial. For the Christian life is all like one of those sweet spring showers in early April, when the rain-drops weave for us a mist that hides the sunshine; and yet the hidden sun is in every sparkling drop, and they are all saturated and steeped in its light. 'The joy of the Lord' is the natural result and offspring of all Christian faith. II. And now, secondly, the 'joy of the Lord' or rejoicing in God, is a matter of Christian duty. It is a commandment here, and it is a command in the New Testament as well. 'Neither be ye sorry, for the joy of the Lord is your strength.' I need not quote to you the frequent repetitions of the same injunction which the Apostle Paul gives us, 'Rejoice in the Lord always, and again I say, Rejoice'; 'Rejoice evermore,' and the like. The fact that this joy is enjoined us suggests to us a thought or two, worth looking at.
