The Longer Topical Studies on this site go over things topically (tracing a subject rather than sticking with a specific part of scripture), and tend to trace topics much wider in overall scope than those covered in the Shorter Topical Studies, which is why they end up longer.
Longer Topical Studies
A video series going through Bible Basics Part 6A (BB6A) on Ichthys, a study of the Christian walk -- the path of spiritual growth and production that we must all walk as believers. The early recordings in this series were the very first video content that I ever recorded, and we were not particularly organized, because wider distribution was not at that point something I had in mind. All the lessons posted in this study on the website, however, correspond to the later videos in the series, once we started to become more organized and focused.
A video series going through SR4 on Ichthys, a study covering the structure and organization of Satan's world system. Satan is the present ruler of this world (only because God lets him, for this short time), and tries by all means to deceive us and distract us from the truth. By formally studying his strategies and tactics, we can learn to see through his illusions, and come to appreciate the spiritual realities that are actually at work in the world.
