2 Bible Verses about Mourning Turned To Joy

Verily, verily I say to you, you shall weep and lament, but the world will rejoice. You shall be sorrowful, but your sorrow shall be turned into joy.

But concerning those who have fallen asleep, I would not have you ignorant, brethren, that you may not grieve, as others who have no hope. For if we believe that Jesus died and rose again, so also should we believe that God will, through Jesus, bring with him those who sleep.
