On the Day of Atonement, the most recognizable facet consists of no food or drink for 24 hours, a means of afflicting the soul to bring about humility. In Scripture, fasting/afflicting one's soul relates to humbling oneself, grief, piety, repentance, and along with prayer, seeking God's will. God commands us to afflict ourselves to spur the motivation to change so 1.) He does not have to force us to change, and 2.) we can grow in in the character image of His Son and ultimately, enter the Kingdom of God. Jesus taught that fasting is an internal, spiritual good work, done in the inner self, by the inner self, for the benefit of the other. Any other kind of fasting has little or no spiritual value. It was a point of contention between Jesus and the Jews (because of their hypocritical fasts to receive public acclaim) and John's disciples (who failed to realize that while Jesus was with His disciples, excessive fasting beyond atonement and other times would be out of place). The Pharisees castigated Jesus for going against their oral Talmudic teachings, thinking it too liberal, too arrogant, too avaunt guard, making them suspicious and resistant to Jesus. But when Jesus makes something new, He returns it to the original spiritual purpose, which was not accepted by their faulty traditions. Metaphorically, the new wine of Jesus' teaching burst the seams of their old wineskins (their 'religious' but hypocritical doctrines). Their fasting did not affect their hearts. They felt no anguish over their sins, no humility or sense of inadequacy before God, no sense of grief for the perverse course of this world, no desire to change at all because they felt no need to. But the fasting that impresses God is a kind that overcomes sin and its effects, resulting in a change in a person's attitudes toward others, making him willing to sacrifice for them, making their lives better.
