We are told that the christian god has sent his only son, who was an innocent person, to die for our evil deeds so that we can be forgiven by him. If we don't accept this free gift of salvation, we will be punished for eternity.
We are told that we can accept this FREE gift of salvation by asking him for it.
Fine, I'll take this free gift.
Guess I get to live in heaven now? That wasn't hard.
Being a free gift, I shouldn't have to do anything to receive it but ask for it. If I have to work for it, it is no longer a free gift. If I have to do anything else to receive it or to keep it, it is no longer free.
So again, sure, I'll take this free gift since it has been offered to me many times.
This thread explains the christian plan of salvation in detail.
Note that I'm not evangelizing.... just posting the christian method of salvation.
