'Joy' in the Bible

not that we rule [like dictators] over your faith, but rather we work with you for [the increase of] your joy; for in your faith you stand firm [in your strong conviction that Jesus of Nazareth—the Messiah—is the Son of God, through whom we obtain eternal salvation].

And I wrote this same thing to you, so that when I came, I would not be filled with sorrow by those who ought to make me glad, for I trusted in you and felt confident that my joy would be shared by all of you.

Great is my confidence in you; great is my pride and boasting on your behalf. I am filled [to the brim] with comfort; I am overflowing with joy in spite of all our trouble.

It is for this reason that we are comforted and encouraged.And in addition to our comfort, we were especially delighted at the joy of Titus, because you have refreshed his spirit.

for during an ordeal of severe distress, their abundant joy and their deep poverty [together] overflowed in the wealth of their lavish generosity.
