If we are all part of the spiritual world, why were we even sent to the physical world temporarily?

​We chose to come here for the growth of our Soul. We were not sent here. Our Souls chose to incarnate at this particular time, as this gender, in whatever part of the world we are in, following the laws of the expanding nature of the Universe, growing and adding to the overall increasing glory.
 
It is difficult to be in the Physical and it would have been much easier to continue in the positive energy of our non-physical being, but that would not have been a growth situation.
