Do God need human sacrifice? The answer is an ambiguous yes and no!
NO! God does not need indoctrinated people to blow themselves up in order to kill other people, under the impression that they do God a service and a favor and will reap generous divine rewards. Those people martyr themselves for eternal condemnation!
THAT... IS FALSE WORSHIP!
YES! God needs humans to sacrifice "their bodies as a LIVING sacrifice" (Rom.12:1) to serve Him by serving their fellow humans.
THAT... IS TRUE WORSHIP!
