Agreed. Collectively speaking, Cain has been murdering his brother over and over, especially within the context of genocidal Marxist Communism and National Socialism. Yet these two bloody regimes will be as nothing compared to the global genocide already in progress via Transhumanism.
In Christ. Born again. No deception. So the early real church (new creation. His Body) celebrated together having all things in common. But Annanias and Saffirias were struck dead for holding back.
Cain failed for not having the required blood Sacrifice. Old testament through. So he thinks getting his brother out of the picture will gain God’s acceptance.
Gave way to murder. Gave way to Lucifer.(as Eve) “ Murderer from the beginning”
The Coming Advent. Lion with the lamb, no more murder “sheep’s in wolves clothing” Born “from above” lit. all in the Commons with celebrated talents. No Lucifer no more murder jealousy. The choices already made now in this life.
“Love your brother” Christ has come in the flesh. (All of First John) In this life.
