Fasting is ment to be a time of solemnity with oneself and God.
Abuses of fasting included: lack of sincerity, wrong purpose, and for show only.
Although many people say that the NT does not command fasting, it can't be said that it is not expected. Fasting is intended to be an avenue of focusing on God. Focus of prayer. Focus of thought. Focus of devotion to God.
Please, be humble to God.
The Lord's humbled . . . John A. Reeves
