I would defineitly agree that there are a large percentage of saints who aren't happy at all.
Nor do they know how to get there.
Some people think that if they are happy, they must be sinning. Because of wierd and off-base teaching, they think that living right is being poor, ugly, not enjoy any sports or clean entertainment, be in a marriage where the person is hitting you, have a bad realtionship with your children and allow other saints to walk all over you.
It's sad, but true.
