SUMMARY
Proper fasting is not mere refraining from food, but a commitment to justice and the poor. This is where God’s people will find life.
ANALYSIS
IsaiahIsaiah, son of Amoz, who prophesied in Jerusalem, is included among the prophets of the eighth century BCE (along with Amos, Hosea, and Micah)--preachers who boldly proclaimed God's word of judgment against the economic, social, and religious disorders of their time. 58 shares the condemnation of hypocritical worship practices found so often in the prophets (for example, Isaiah 1:12-17; AmosProphet to the northern kingdom who condemned Israel's oppression of the poor, calling for justice to "roll down like waters." 5:21-24; Micah 6:6-8). JesusJesus is the Messiah whose life, death, and resurrection are God's saving act for humanity., too, was critical of fasting for external reward (MatthewA tax collector who became one of Jesus' 12 disciples. 6:16-18). Proper fasting, says Isaiah, is to loose the bonds of injustice, let the oppressed go free, feed the poor, and clothe the naked. All of this is just what God announced as the mission of CyrusPersian leader who allowed Jewish exiles to return home. and the servant in Second IsaiahSecond Isaiah refers chapters 40-55 of the book of Isaiah. This work was likely written during Israel's exile in Babylon (597-538 B.C.E.). Second Isaiah includes poetic passages of hope as well as descriptions of the Suffering Servant. (42:6-7), and it will be the commission to the speaker of Isaiah 61:1-3. In other words, fasting is not simply a ritual exercise done by an individual for his or her own benefit; by freeing the worshiper from concern for the self, fasting partakes of God’s mission of justice and liberation for all people, thus making new both giver and recipient.
The Hebrew text of vv. 10-11 makes clear how this works in its repeated use of the word for “soul” or “self” (Hebrew nefesh): “If you offer your nefesh [your self, your soul] to the hungry and satisfy the nefesh of the afflicted.…The LORD will…satisfy your nefesh in parched places….” In other words, as you pour yourself out for others, you will find yourself–or, as Jesus said, “Those who find their life will lose it, and those who lose their life for my sake will find it” (Matthew 10:39).
The text includes another amazing promise: “You shall cry for help, and [God] will say, Here I am” (v. 9). “Here I am” is the typical and appropriate biblical response of a person called by a superior or by God. In this book, it was Isaiah’s response when God commissioned him to be a prophet (see the discussion of Isaiah 6, above). But now, surprisingly, God takes those words of quintessential human response into God’s own mouth. Now, God says, “Here I am”–saying, as it were, “I am at your disposal.” This happens three times in the latter part of Isaiah (here; 52:6; 65:1), demonstrating the remarkable inclination toward incarnationIncarnation literally means "embodied in flesh." It is a Christian doctrine, based on the witness in John's Gospel, that God's Word was made flesh in the person of Jesus Christ. The Apostles' and Nicene Creeds confess the central importance of the incarnation of Jesus. of God, as portrayed in this material.
