Luke 18:12 I fast twice a week; I give tithes of all that I possess.’
Boasting about your fasting is just wrong on so many levels! We should fast in order to show Christ we mean what we say, not to show others we do.
It should not be taken as a prideful time because man cannot live without food!
God told man in the very beginning what he should be willing to sacrifice and further taught us to willingly give for the upkeep of the church.
Boasting about how much you can give is nothing more than boasting of your earthly riches.
