Salvation means that you are getting saved from something to something. Unfortunately there is no in-between or a neutral place there you can hide. All humans have at some point done something sinful (because of our sinful nature) and because of that we don’t have access to God any longer in the way God intended us to from the beginning.
So now instead of having a relationship with God we have been sold out to sin and our soul’s enemy is having a claim on us, which is the devil.
So if you die without God you will go to hell and will be tormented forever.
I have never ever heard from someone who has gone from darkness to light have any regrets for that. Usually they wish that they could have known the Lord Jesus earlier in their life.
So how to get “saved” and what “proof” do we have that God is a reality? More about that later.
