My latest wordpress plugin is a plugin that automatically creates links to bible gateway from reference in wordpress posts. You can get it here:
Its not perfect yet as its a modification of wp-bible, but because it uses bible gateway it has premium translations like NIV, NLT, The Message, and many more! By default it will reference which ever translation the user last looked up using in biblegateway, but this can also be specified in the options. It should handle references at least like John 3:15-16 and some others and I’m hoping to refine it further as it goes on.
Fix so that all links now include version, not just some
Added option to open links in a new window
Bible version to link to can now be specified in the options
Fix for bible references like John 3 verses 15 to 16
