I was talking to a Christian who told me she fasts the traditional way in Lent. No food or water from sunrise to sunset. She was the first I had met who actually abstains from food and drink for a significant period of time.
Other Christians I know choose to give up one food e.g. chocolate, wine, tea, coffee. One Christian told me she gave up Facebook for Lent.
The Christian who said she fasted the traditional way told me she gained many benefits such as spiritual closeness to God, self discipline, greater self control.
It did make sense. Giving up Facebook doesn't seem likely to bring many benefits although may it did for that one person.
I wonder why it became diluted and whether Christianity has lost its followers by allowing most things it did not used to.
