If you are going to choose to journal digitally, you'll need access to an online or computer-based Bible. Different journalers will swear by different ones, so it's all about what fits your needs. Most of the ones available are free and have several translations, so you should find it easy to choose the one that is right for you. You wOlill want one that is easy to copy from and paste onto your document.
Bible Gateway and ESword are the ones I use. Bible Gateway, of course, has a web site and you can access it just about any time you want. ESword is downloadable software. It is free for the PC, but costs somewhere around $10 for the Mac version. It has a few translations that come with it, but if you want more you'll have to buy them to add on.
