Pope Shenouda III
Fasting, therefore, is a sacred, idealistic, and extraordinary act. It requires a special spiritual planning to match its holiness. When a fast begins, we feel that we have entered a time of exultation and started extraordinary days of self training in living a life of perfection. Therefore, these days should not pass as other days do, for they constitute a new phase in our relationship with God - a phase that we go through with new feelings and spirit.
It is true that all the days of our life should be sacred. However, fasting days are more so than others. If we conduct ourselves well during these days, we shall attain the holiness for the rest of our life. It is a time when we devote ourselves, as much as we can, to God and deepen our relationship with Him..
