This is one of the most misunderstood chapters in the Bible, but David believes it is a picture of the great triumph of Jesus over Satan, who in this chapter and the next is called the "Chief Prince" of the nations. Jesus defeats Satan at Calvary and takes the nations back through his atoning work. Gog and Magog are not some combination of Russia, and Iran attacking Israel. That idea is particularly tenuous and as is based on just about no evidence whatsoever.
