Satan's Origin & The Worst Sin of All Sins
"ONLY GOD can explain where evil as we know it in the world came from. He gives the ONLY reliable, eye-witness, authoritative accounting of how EVIL, sin, decay, and destruction all started. Two chapters in the Scriptures give us the framework to understand where the ORIGINAL sin of pride started. Those chapters are Isaiah 14 & Ezekiel 28. Join me for a jet tour of the ORIGIN of EVIL." from video introduction
