Your bible certainly has a strange way of explaining things, so I will explain it is a way everyone will understand. @MrGordon's, Lords and Masters at the JW HQ, the Watchtower offices, do have "a strange way of explaining things" but no more so than your JW way... The kingdom of God also known as the Galactic federation of light has sent its representatives to earth embodied as humans to join the fight against the devil also known as the dark the dragon reptiles supported by Hamas and many other dark beings around the world.
We human divine souls are considered to be the most powerful of all and are important to all the other worldly worlds as we will become their greatest beings of divinity when we succeed in ascending to the heavens, so they had to save us as we are them, we can save them with our learned divinity. I suppose this is on par with @MrGordon's JW belief that we were created in the image of God and that the select will be saved by this God. It seems that there is a need to stroke our egos.
