2 Bible Verses about Mourning Turned To Joy

I tell you solemnly that you will be weeping and wailing while the world is rejoicing; you will be grief-stricken, but your grief shall be turned into gladness.

But I would not have you ignorant, brothers, about those who are falling asleep. You must not sorrow like other men, who have no hope. For if we really believe that Jesus died and rose again, so even so will God through Jesus bring with him those also who have fallen asleep.
