'Suffering' in the Bible

For our momentary, light suffering is producing for us an eternal weight of glory far beyond all comparison

I have great confidence in you; I take great pride on your behalf. I am filled with encouragement; I am overflowing with joy in the midst of all our suffering.

that during a severe ordeal of suffering, their abundant joy and their extreme poverty have overflowed in the wealth of their generosity.

For I do not say this so there would be relief for others and suffering for you, but as a matter of equality.
