Isaiah 55:1-9
Invitation to the Thirsty
October 18, 2026

Overview & Insights
“Seek the Lord while he may be found, call on him while he is near.” (Isaiah 55:6)
An Invitation to Sing: Once again a return to a focus on Ms Jerusalem follows the servant passage, as happened after 49:1–6 and 50:4–11. There were hints there that Ms Jerusalem’s restoration was the correlate of Ms Babylon’s humiliation in chapter 47. Chapter 54 is the systematic exposition of that theme. The prophet takes up five images of Ms Jerusalem which once again resume the themes of the people’s prayers (we are like a childless and abandoned woman, the victim of angry abuse—literally, we are a battered and insecure city) before coming to a striking conclusion.
