Ecclesiastes 7:3

Now I rejoice, not that ye grieved, but that ye grieved to repentance; for ye grieved in a godly manner, so that ye received damage by us in nothing.

Happy are ye that hunger now; for ye shall be satisfied: happy are ye that weep now; for ye shall laugh.

Wo to you that are full; for ye shall hunger: wo to you that laugh now; for ye shall mourn and weep.

Verily, verily I say unto you, Ye will weep and lament; but the world will rejoice: ye will be sorrowful; but your sorrow shall be turned into joy.

And not only so, but we glory in tribulations also,

For our light affliction, which is but for a moment, worketh out for us a far more exceeding and eternal weight of glory:

For they, verily, for a few days chastned us as they thought good: but he for our profit, that we may be partakers of his holiness.

My brethren, count it all joy, when ye fall into divers temptations, Knowing that the trying of your faith worketh patience.

Draw nigh to God and he will draw nigh to you: cleanse your hands, ye sinners, and purify your hearts, ye double-minded.

Sorrow is better than laughter: for by the sadness of the countenance the heart is made better.
