Isaiah 7.3, 57
Part 7: The New Jerusalem (Isaiah 56–66) • Focus: The outworking of God's vision in the post-exilic community and its ultimate fulfillment in the new heavens and new earth. • Week 25: Chapters 56–59 - The Ideal vs. the Actual Community ◦ Address the realities of the community after the return, contrasting God's ideal (a worldwide, inclusive "Sabbath-people") with their actual failings and sins. ◦ Discuss the confession of sin and the need for God's intervention.
Verses 6–12, describing how a fast day should be used, fall into two parts, each specifying activities (6–7, 9c–10b) and promising blessings (8–9b, 10c–12). First, a fast day is for the creation of a caring society (6), meeting needs (7a–c) and family welfare (7c), and it brings consequent personal blessings: new beginnings (8a), personal restoration (8b), security (8cd) and a free-flowing relationship with the Lord (9ab).
Secondly, a true fast is for correction of inhuman conditions (9c), banishing mischief-making (9d) and meeting needs (10ab), and it results in clear guidance in life’s perplexities (10cd–11a), renewal (11b), durability (11c), ever-fresh resources (11de), restoration and continuance (12). What seems like deprivation—fasting—is actually enrichment when used according to God.
