Never said they did.
I know.
It does if a person's life has been so awful that they can't "see" God - if they regard "love" as sex or abuse, if they had a dad who was an alcoholic and beat them, and they have no idea what a loving father is like. If someone with that kind of background were to hear the Gospel, they MIGHT not be able to accept; blame God for not stopping the abuse etc - I've heard enough people saying, "if God really loved me, he would/wouldn't have ....."
I haven't had anything like that kind of background, but it took me years to understand, and accept, that God loved me - not because I did anything right with my endless church going, but simply because he created me and he IS love. If I had taken my own life when I was a teenager, or a few years later when I had M.E and lost my job; would I have been saved, even though I didn't fully grasp the Gospel or how much God loved me? I, at least, went to church, read the Bible and prayed - sometimes I was scared of God's disapproval if I didn't.
Some people are so hurt or damaged by their background, or life, that they wouldn't go near a church and might be unable to respond to the Gospel if they heard it.
What would happen then? I don't know; I'm not God. But I trust and know his mercy and love.
