What I wanted to say, but couldn’t find the words at the time, was
God’s great plan was the creation of a new community with whom he would remake the entire cosmos. To do it all he first needed to deal with our sin. Dealing with sin and it’s effects is critical and essential, without it there would be no re-creation, BUT DEALING WITH MY SIN WAS NOT HIS SOLE PURPOSE. God and his plans for his creation are infinitely bigger than that.
I’m not sure how he would have reacted.
