The concept of reasoning with God has a long history in Scripture. We see the way that humans sparred linguistically with God in Abraham's bargaining for Sodom, in Moses' logic to save his people, and throughout the book of Job.

I wondered about Isaiah's statement in 1:18, “Come, let us reason together, says the Lord, Though your sins are like scarlet, they shall be white as snow.”

Is the act of reasoning here a prelude to introducing the subject of redemption? In other words, is God saying, “Let's talk about something; specifically forgiveness of your sins”?

Or can it be cause and effect?

Is it possible that the act of reasoning with God is a trigger that causes His action: Does reasoning with Him move Him to action?
