Fasting

Refraining from certain kinds of food or drink (often refraining from eating meat) as an act of self-denial in order to strengthen one’s will power, resist temptation and offer a spiritual sacrifice to God. Official days of abstinence from meat for Catholics are Ash Wednesday and Good Friday. Fasting, together with prayer and almsgiving, are traditionally recommended to foster the state of interior penance. At the same time they constitute a concrete support (spiritually and materially) for the work of Evangelization. Very often in the Bible, fasting is directly connected with Evangelization, as the book of Acts refers about the sending of Barnabas and Saul from the Church of Antioch:
 
“One day, while the Christians in Antioch were worshiping the Lord and fasting, the Holy Spirit said, ‘Set apart for me Barnabas and Saul for the work to which I have called them.’ Then after fasting and praying they laid their hands on them and sent them off.(Acts,13: 2-3)
