Okay. Then live a life of hedonistic delights, sin a lot and often because that's what humans do, and then call a priest to give you Last Rites on your death bed, confess your sins, and all will be forgiven. Gee, wish I had known this earlier, I missed so much fun.
That would be extremely risky, since I don't know when I'm going to die. Jesus had something to say about that, too. Something about being ready to die at any time.
