Honestly, I think if you actually knew about God and Jesus and chose to not accept him, I think it would be a lotttttt worse than you in comparrison to some tribal group that have never heard of religion in their lifetime.
Again, how would being virtuous save you? Let's say, you murdered 1 person intentionally. How can you, as a murder, go to heaven?
Serve time in jail? If so... then "how much"?
Donate to charities? If so... then "how much"?
Donate your time to volunteer associations? If so... then "how much is enough"?
Help the poor? If so... then "how much"?
See where I'm going?
the alternative is to become a Christian.
Disclaimer: You do not need to go to church to be a Christian. You do not need to read a Bible daily/monthly/yearly to be a Christian. You do not even have to agree with all of the Christian teachings (ex:evolution vs creationism).
Honestly, it is not hard to become a Christian
Step 1: Admit you have sinned in your life.
Step 2: Make a prayer to God. Here is an example prayer:
Lord Jesus, I admit I am a sinner. I need forgiveness. I am sorry for my sins and I don't want to sin against You anymore. I believe You are the Son of God and You died on the cross for MY sins. I also believe that you rose from the dead so that I, too, may have victory over the grave. Please forgive me now Lord and cleanse me. Come into my heart and give me a new life. Thank You, Jesus, for shedding your blood for me and for hearing and answering my prayer. In Jesus Name I pray, Amen.
Step 3: You're done! Congrats brother/sister. I'll see you in heaven!
Technically, if you think about it...
You really have nothing
to lose if you said that prayer. If you truely believed those words at one point of your life and admit it to God, you're saved. And, salvation can never be taken from you no matter how bad/non-Christian-like you act. I don't care if you murder 1,000,000,000 people after you truely said those words. You'd still go to heaven because God is graceous.
