Most Christians would consider biblical fasting a very unpleasant undertaking. Considering the complexities of the affliction offered by fasting might better help to understand its value. In our passage, the people of God determined to fast so that they might afflict themselves before the Lord. Several other passages discuss this affliction in even more detail. Isaiah 58:3 and 5 describes the affliction as not merely an affliction of the flesh, but also an affliction of the soul. Additionally, we learn that fasting humbles (Psalm 35:13) and chastens (Psalm 69:10) the soul. Fasting involves much more than merely opposition to one’s flesh. Fasting directly afflicts, chastens, and humbles the soul. Perhaps this is why it is so difficult to fast and so beneficial to do so.
The passage may appear to directly equate obedience and submission together, but each word conveys a separate and distinct concept. Although today's passage includes both obedience and submission, it is important to recognize that these two words involve separate acts. Earlier studies noted a twofold definition of obedience: first, having an attentive ear, followed by acting upon what has been said. Dividing submission into two parts helps to better understand it too (sub + mission). The prefix sub means under (thus a submarine travels under the water), and the root word mission means to be sent out. Obedience, therefore, emphasizes the act of hearing and doing, while submission emphasizes the act of placing oneself under the authority of another.
