If there is any certain mark of the abiding presence of the Holy Spirit in the soul, if there is any visible pledge of future happiness destined for man, assuredly it is lightness of heart and joy of spirit. On some souls the black clouds of despondency and gloom never settle, sorrow may touch them with her sable wings, grief may blanch the hair and early care rob the step of its youthful spring; but the joy which is not of this earth ever shines upon the brow of such a soul, and the heavenly peace and calm within shine brighter through the flood of tears which are wrung from a sore-stricken heart.
