You've asked this question already. And it has been thoroughly answered an debated already. John 3:3, John 3:5, Acts 2:38. By having faith in Christ, and by accepting that he died for the forgiveness of your sins. That's how.
By being a good person.By following the ten Commandments and making an effort in the fundamental option of your life to treat others well without basing it on money,or status,or possessions.By being selfless when its easier to be the other way.
peacefully:-) but for real i think your deseaced love ones come to your dead body. and retrieve you soul carrying you up. and you live happily ever after :-) .but if none loved you or you are not worthy you are sent down, not to hell but in a cold dark place where you must fight for survival and you will always feel hurt and cold and pain and can never wait for death because its never coming again... your already dead...... i so just ripped off the book breathe XD But i really think that happens
You have to accept Jesus into your heart, and know he is your saviour, and that he died on the cross for you. Then, you should grow in your relationship with God, and your main purpose of life would be to worship him. But, no matter what you do, if you just believe in him, you will enter the kingdom of heaven when the time comes for you to leave the earth.
Most people believe they will go to heaven when they die... Their hope is fostered by the comforting words of many preachers, priests, and rabbis Their hope is based upon the idea that heaven is for all believers, or for those whose good works outweigh the bad
But are such hopes well-founded? Will most people go to heaven when they die? Is salvation based upon good works? Is it based upon faith only?
In His sermon on the mount, Jesus gave some ominous warnings... Few, not many, would be saved - Mt 7:13-14 Many religious people, including some believers in Jesus, will learn that they too will be lost! - Mt 7:21-23
