Hi, Ken. I'm back
I think a good way to answer the question "how does God get glory by allowing Satan to corrupt his creation?" may be to make it personal. Hope it works for you.
The concept of God's grace is summed up in him giving me good I do not deserve and foregoing the punishment I do deserve. Therefore, in order to show me grace, it was necessary I have no claim on expecting his goodness and good reason for deserving punishment. The corruption of his creation is how I ended up in such a position. The work that Jesus did was the means he provided to show me grace. (BTW, Jesus was the plan even before the corruption of creation; he was not a reaction to the Fall.) God's glory is very much seen in the spectacle of his grace. There is one way God's glory is seen via the corruption of creation. The Bible has the phrase "to the praise of His glorious grace." It is largely on that phrase and what precedes it that I make this claim.
Reasonable? (Not expecting your agreement; just asking if I make sense.)
