2 Bible Verses about Mourning Turned To Joy

Truly, truly do I say to you, that ye will weep and lament, but the world will rejoice; ye will be sorrowful, but your sorrow will be turned into joy.

But we would not have you ignorant, brethren, concerning those who are sleeping, that ye may not sorrow, as others do, who have no hope. For if we believe that Jesus died and rose again, then also will God, through Jesus, bring again with him those who have fallen asleep.
