“I will lay waste mountains and hills,
and dry up all their herbage;
I will turn the rivers into islands,
and dry up the pools.
“I will lead the blind
by a road they do not know,
by paths they have not known
I will guide them.
I will turn the darkness before them into light,
the rough places into level ground.
These are the things I will do,
and I will not forsake them.” (Isaiah 42: 15, 16 NRSV)
This is a powerful, irresistible, transformative resolve, to be undertaken with a high level of emotional intensity. It is a burst of generativity that is going to change everything and create a newness. This is a God who will not forsake: “I will not forsake them” (42:16); “You shall no more be termed Forsaken” (62:4). In this resolve to new creation, YHWH promises to overcome all forsakenness and abandonment known in Israel and in the world. When creation is abandoned by YHWH, it readily reverts to chaos. Here it is in YHWH’s resolve, and in YHWH’s very character, not to abandon, but to embrace. The very future of the world, so Israel attests, depends on this resolve of YHWH. It is a resolve that is powerful. More than that, it is a resolve that wells up precisely in tohu wabohu and permits the reality of the world to begin again, in blessedness.

Note: The phrase “tohu wabohu” is a reference to the Hebrew phase used in Genesis 1:2, where before God’s creative action, the world is spoken of as being “formless and empty” (NIV). I have highlighted the phase in bold in the text below:
וְהָאָרֶץ הָיְתָה תֹהוּ וָבֹהוּ וְחֹשֶׁךְ עַל־פְּנֵי תְהוֹם וְרוּחַ אֱלֹהִים מְרַחֶפֶת עַל־פְּנֵי הַמָּיִם
