Intro

If someone doesn’t believe in the lord Jesus Christ then they are not saved.

John 3:18 KJV
He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.

If they are not saved then they won’t go to heaven when they die.

If they won’t go to heaven when they die then they will end up in the lake of fire when they die.

If they go to the lake of fire when they die then it would have been better for them if they had never been born.

So to prophecy that someone is going to burn in hell is easy and to prophecy that it would have been better for someone if he had never been born is easy.

Comment

Are you saying that we need continuous faith to go to heaven and that someone that stops believing for a bit loses their salvation?

No I am not saying that. I do believe that salvation happens in an instance when someone believes on the Lord Jesus Christ.

But for a person to try to find out if someone else is a believer or not. A way to do that is to ask the other person if they believe in Jesus Christ and see what they answer. If they answer no they are most likely an unbeliever.
