2 Bible Verses about Mourning Turned To Joy

In most solemn truth I tell you that you will weep aloud and lament, but the world will be glad. You will mourn, but your grief will be turned into gladness.

Now, concerning those who from time to time pass away, we would not have you to be ignorant, brethren, lest you should mourn as others do who have no hope. For if we believe that Jesus has died and risen again, we also believe that, through Jesus, God will bring with Him those who shall have passed away.
