Passage context
Isaiah 55 follows the servant and suffering themes before it and turns to a public call: come, listen, seek, and live. It speaks to people who have no money and no life left to spend, and it offers food, water, mercy, and an everlasting covenant. The last verses say God’s word works like rain and snow, bringing fruit instead of emptiness.

Justin Martyr, Theophilus, Novatian, and Victorinus used it for Christ’s call to the nations and for the open offer of life to thirsty people. Their reading matches the passage’s plain meaning: God freely calls people to seek him and promises that his word will not fail.
