Except in Galatians 3:13.
No, Galatians 3:13 is certainly not an exception.
Jesus DID become a curse for us.
But what I said was that there is not a verse in God's Word that states God judged Jesus as a sinner.
The problem with arguing theories rather than Scrioture is that theories are subjective where Scrioture is not.
You can explain all day long that the Bible teaches that God judged Jesus as a sinner, and others can explain all day long that the Bible teaches that men can choose salvation without the work of the Spirit, or that God created man through evolution, or the gap theory....whatever.
But all of that is subjective where Scrioture itself is objective.
Here we are not even talking about differing interpretations. We are talking about one man, or one group's, theories.
It doesn't work to provide a verse to "prove" what the verse does not say. That only works when preaching to the choir as they already accept the theory and merely look at Scripture to prop it up.
