makairos
What it means
A prayer that reasons from creation to confidence. The God who made the heavens and the earth is not stretched by anything smaller than that, and everything is smaller than that.
Jerusalem is under siege and Jeremiah has just bought a field, a sign that the land will be inhabited again. This is the opening of his prayer afterward.
Where it addresses you
The problem looks impossible on paper.
You are being asked to act in faith while the walls are closing in.
