2 Bible Verses about Mourning Turned To Joy

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

Now I would not have you ignorant, brethren, concerning those who are fallen asleep, that ye be not afflicted, as the rest [of mankind] who have no hope. For if we believe that Jesus died, and rose again, so also those that have fallen asleep for Jesus shall God bring with him.
