Verily, verily, I say unto you, That ye shall weep and lament, but the world shall rejoice: and ye shall be sorrowful, but your sorrow shall be turned into joy. – John 16:20

Jesus promises that He will so come and reveal joy to the sorrowing soul, that the face shall fill up again: the eyes that were dull and cloudy shall sparkle again, and the countenance, yea, and the whole person shall be once more radiant with the beauty which sorrow had so grievously marred. I thank God I have sometimes seen this change take place in precious saints who have been cast down in soul. There has even seemed to be a visible beauty put upon them when they have found peace in Jesus Christ, and this beauty is far more lovely and striking, because it is evidently a beauty of the mind, a spiritual lustre, far superior to the surface comeliness of the flesh. When the Lord shines full upon his servants’ faces, He makes them fair as the moon, when at her full she reflects the light of the sun. A gracious and unchanging God sheds on His people a gracious and unfading loveliness. O mourning soul, thou hast made thine eyes red with weeping, and thy cheeks are marred with furrows, down which the scalding tears have burned their way; but the Lord that healeth thee, the Lord Almighty who wipeth all tears from human eyes, shall visit thee yet; and, if thou now believe in Jesus, He shall visit thee now, and chase these cloudy griefs away, and thy face shall be bright and clear again, fair as the morning, and sparkling as the dew. Thou shalt rejoice in the God of thy salvation, even in God, thy exceeding joy. ~ C.H. Spurgeon
