Great to see that the MacArthur Topical Bible is available through Mantis. The current resource available is in the NKJV. Is there any possibility that this resource would be offered in the NASB version? Thanks!

Sorry, but we don't have that version available. However, you can have any version of the Bible work with the MTOP resource. Whatever version of the Bible you last selected (say, NASB in this case) will be used automatically to preview any verse links. Try it and see -- just switch to the NASB, then switch back to MTOP and click on some verses.
