Hi Hero,
I think it's great that you want to do this. However, keep your "audience" in mind. I'm assuming that you intend to use this tract for non-church people. They don't understand Christian-speak ("repent", "maranatha") and for most people the language of the KJV will turn them off. I strongly suggest you use a modern Bible version and language that they will understand.
As for layout, if you fold your A5 sheet in half, you will have a little "booklet", which looks a bit more interesting than a single sheet. If you have MS Publisher, you can do this automatically - otherwise you just need to lay out your pages in the order: page 4 on the left of the first sheet, page 1 on the right of the first sheet, page 2 on the left of the second (reverse) sheet, page 3 on the right of the second sheet.
I pray God will bless you mightily as you seek to reach out for Him.
Lynn
