In Isaiah 1:18, God says, “Come, let us reason together, saith the Lord. Though your sins be as scarlet, they shall be white as snow. Though they be red like crimson, they shall be as wool.”
As we discussed last week, to reason with God means to come to the Lord, allow Him to convict you of your sin and correct your sin, and then God will cleanse you and forgive you of your sin.
In Isaiah 6, we see what this looks like, as Isaiah has his reasoning moment with God.
