Acts 23:14 “They went to the chief priests and the elders and said, ‘We have taken a solemn oath not to eat anything until we have killed Paul.”
False fasting doesn’t lack submission to a higher authority (the Sanhedrin).
False fasting can be a united front. (We have taken …)
False fasting doesn’t lack commitment. (…not to eat anything …)
False fasting can look godly. (…solemn oath …)
False fasting wants change. (…killed…)
False fasting is not what Isaiah (58:4) calls for: Is not this the kind of fasting I have chosen: to loose the chains of injustice and untie the cords of the yoke, to set the oppressed free and break every yoke?
The reasons for fasting can appear to be spiritual but in fact it can all be false.
