it can all be summed up by EPHESIANS 2:2
"Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the SPIRIT that now WORKETH IN THE CHILDREN OF DISOBEDIENCE"
This is a spiritual battle. We are here because we turned from God the Father. With this, we were turned in two, one right side up & the other upside down (think Jesus & Peter crucifications). Jesus' mission was to make us WHOLE, to defeat DEATH & give us a way BACK HOME to our Father in Heaven.
The spirit of Lucifer's agent, Satan, works within all these people that wish to keep us from Christ.
