Satan is a murderer. Of course, he is also a spirit, but a spirit that exercises what control he can, considering that he is not omni-present like God. So directly or indirectly we should expect that he gets men to build things to kill with. Still the point made is a very good point. God is the creator. So what spirit might be behind the building of things we use to help others?
We are told that God put before us both good and evil and that we need to choose good. We don't battle with people but powers, principalities, and the dark forces of this world. So, what spirits are behind those looking to conquer, kill, take over power by force or lying, and so on?
Are we praying enough, considering that it seems we are seeing more weaponization, threat of forceful conquering, and many lying to get in or keep power?
Of course, it is also written that knowledge will increase, and some vaccines were created that though not perfect seem to help many people by the use of increased in knowledge.
Still, if we really want good advice and counsel, we should actually seek the voice of the Lord.
