Has human nature changed since the time Paul wrote to the Galatians?
No, human nature has not changed one iota since Paul wrote to the Galatians. The same spiritual conflict between the Holy Spirit and the evil spirit, including the spirit of Antichrist, remains in the world. Satan still opposes the truth using whatever means he can, just as he did then.
Les explains that the human race hasn't changed one iota since Paul wrote to the Galatians. The world faces the same two spirits: the Holy Spirit or the evil spirit, and the spirit of Antichrist is already in the world. Satan's demons originate in satanic powers, and Satan promotes even beautiful, cultural, and enlightening things to keep people from the truth; he doesn't care what he uses.
