It really helps when needing to look up things.
As I mentioned, I have a Bible app (Bible Study from Olive Tree Bible Software) on my tablet computer along with about a dozen versions of the Bible. BTW, both the app and the King James version of the Bible were free. Not only can I look for a word, but I can look for multiple words or for a phrase. Very handy!
I like the electronic gadgets and if I could afford them I would have plenty.
On the other hand, sometimes it is easier just to check things in a book, especially if it is alphabetical.
