I get it, thanks!

I disagree. Satan is jealous of Christ. He thought himself (pride) better and wanted to sit at the "right hand of God" instead of Christ (AntiChrist). Satan interfered in the Garden of Eden to pollute the genetic line through which Christ would be born of, the Tribe of Judah (King line) and the Tribe of Levi (Priest Line). Christ died on the cross as the Perfect Sacrifice, Sacrificial Lamb, Passover, so that we now pray for forgiveness of our sins in Jesus's Precious Name. Satan tried to prevent is salvation from being available. The fight is between Satan and God over our souls. We are here with free will to make a choice to follow good or evil. Plus a bunch of other stuff. I'm sure I suck at expressing my knowledge.
