I typically promote the books from the e-store, but there are helpful, instructive teaching aids as well such as the easy-reading e-charts. Go to that page and click on the charts to enlarge it for detail.
There are also e-pamphlets (tri-fold), which you can print off and freely distribute as many as you like.
And there are mp3 audio files that can be downloaded that teach various aspects of premillennial and prewrath eschatology.
(If you do purchase any of these e-products and do not immediately receive an email containing the download links, be sure to check your spam box.)
If you want to receive every e-product for free, and future e-products, you can become an Eschatos Partner, which is a monthly support program.
