Why is it so hard for people to look beyond this life ?
Because there is nothing beyond this life, your life. When you die there is nothing of you to physically carry on to some sort of heaven/paradise/afterlife.
God has promised to save/ to heal our soul and save us from eternal death.
Why do we need saving? Saved from what?
Nothing we ever face in this life however horrific it may be will come anywhere close to what an eternal death will be.
And why would God, a figure of supposed perfect goodness, sentence his creations, man, to endless, eternal death and torture? It simply does not make any sense.
...but rest assured there IS a God and he sAVES SoULS...
"Extraordinary claims require extraordinary evidence."
If there is a god and these things you call souls and these things called souls need saving by this thing called God then where is the evidence for those things? How did you prove it to yourself?
Or, I wonder, did you just grow up assuming everything you heard in church was correct?
