I have now obtained permission from the Lockman Foundation to include the entire texts of Isaiah and Ezekiel in the NASB as observation worksheets in this web site. You can print both the different observation worksheets along with the actual lessons to use as you go through the studies. Some of the observation worksheets are at the end of a lesson, others are at the end of the first lesson in a section. I have not included Revelation worksheets. For the Revelation study, you will have to use your Bibles.
I have also added the in-class charts I used for each lesson in my lectures for Isaiah and Ezekiel. These are at the end of the individual lessons. As of right now, the Revelation in-class charts have not been loaded. If you want to look at them, I can send them to you in a separate email as attachments. Send me an email at Mgrinstd@aol.com requesting the in-class charts for Revelation if you would like to have them. For the Isaiah and Ezekiel studies, be sure you reference the in-class charts after doing each of the lessons as they will help you remember and clarify the material in the lessons.
