I used to think that myself, I was an atheist for 31 years, I had this guy I went to school with he was born again and he told me I was going to hell if I didn't get born again and I laughed at him, and about 4 years later I was born again by the conviction of sin John 16:8-9 because my mom had prayed for me for 16 years, so when I moved back to my hometown I phoned him right away to tell him the good news and we've rejoiced, easy peasy for some and fair warning for others
