Isaiah 1:18

The context

Isaiah 1 opens with a lawsuit: the heavens and earth are called as witnesses, Israel is described as a sick body, and the worship of the temple is rejected as noise. Verses 16 and 17 command washing, ceasing evil, learning good, and seeking justice. Verse 18 follows that command with an invitation to argue, and verses 19 and 20 give the two outcomes.

What it establishes

The verse establishes that the dispute is legal before it is sentimental. The invitation is to reason together, and the offer that follows concerns sins made white as snow. It is addressed to a guilty party who has just been told what to do, not to a neutral inquirer.

What it does not establish

It is not an invitation to a detached debate. The verb means settling a case or reproving, and the setting is a covenant lawsuit with a verdict in view. Nor does the verse teach that sin is only a stain; the chapter demands hands that stop doing evil.
