|Hi. I'm Fyn. I am always happy when folks are trying for Rising Stars!
To be completely honest, I am not sure that this was a convincing, persuasive argument. First off, there were three questions asked versus convincing 'Malcolm' of one answer. And, you never 'really' answered the initial question of WHY the world (questioning the word choice here, given your answer) is brighter on the other side. Your initial question was the point that should have been being defended. Not his subsequent questions.
The use of the word 'world' is an issue for anyone who has event the dimmest concept of heaven - which is where the essay is leaving. If it had been a world with two sides or perhaps a world pre and post dissent etc, then 'world' would have been appropriate.
While you have good answers (in a sense) to subsequent questions you posed, this then is problematic because you are basing the responses on one book. Not trying to take anything away from your beliefs, here. But in a persuasive essay, you need to back the supposition with a preponderance of the evidence. Using the Bible - which for you is key, you must remember that it might not be in all cases, not as a book of facts which are provable.
Tackling a subject such as religion in a persuasive essay is extremely difficult. At the end of it, you need to have convinced someone entirely. Given your initial question, my responses, had I been Malcolm, would have been:
1. What 'world?' Another planet?
2. How is it brighter? Why?
3. Brighter still includes dark vs saying 'There is an absence of dark on the other side.' <--- as an example.
Malcolm wasn't used as an adversary rather as a conduit to help the first speaker. He went along with everything said rather than questioning.
There were a few typos scattered, such as, Bible speaks about what will happen? That is a declarative statement; not a question.
The statement: The Bible is The Word of God. It tells about the time when Jesus walked on this earth. He died, rose again,
and will walk among us again when he returns to earth. is not totally even a correct statement. The New Testament is, but the Old Testament is not about 'when Jesus walked on this earth.'
A persuasive argument must provide answers in such a way that readers cannot question the answers given.
I really hope that this helps you understand more about writing persuasive arguments/dialog. If so, then the entire experience has proven to be a learning experience and that is a good thing! :)
