The purpose of a biblical fast is not to lose weight, but rather to gain deeper fellowship with God. Anyone can fast, but some may not be able to fast from food (diabetics, for example).
Lengo la kibibilia la kufunga sio kupunguza uzito, bali kupata ushirika wa ndani na Mungu. Mtu yeyote anaweza kufunga, lakini wengine huenda hawataweza kufunga kutoka kwa chakula (Wenye ugonjwa wa sukari).
