Being a writer, I would probably combine the Christian journaling with writing tips, etc. Every time I heard someone say something different, I would record it to use later in a novel, article etc. The same with special things said from a Christian speaker. We tend to forget things that make great writing.
A Journal might contain pages just for that purpose.
Then events of the day and my feelings about them would be the next journal entry.
I would prefer it lined and about the size of desk date book.
Hope that helps.
