i also am an evangelical participating in lent for the 2nd year in a row.last year it was a great time of growth for me as a new Christian.lent is a 40 day fasting period to commemorate the 40days in the dessert by our Lord.fasting is absolutly biblical.ash wednesday is called that because we are suppose to remember that from dust we became & to dust we will become.i think sometimes as evangelicals we dont do certain things,not to be right or wrong,but to not be Catholic & i think that is rediculous.
