If we are all going to die and are souls are going to heaven or hell for eternity shouldn't we all be worried?

You shouldn't be worry if your a good person. If you're a bad person, you need to think about changing yourself to be a good person, or else you will be sent to hell when you die. If you die as a good person, God will protect you and you will have a great life in heaven and explore interesting places.

Regarding the person above me, you can't get into heaven by being a good person. Going by the 10 commandments we are ALL guilty in the eyes of the Lord the one way to be saved is through the perfection of Jesus's death on the cross. God is just He lets no sinful man into heaven that is why you need to repent and trust in Jesus Christ as your Lord and savior, not just try and be a good person because its impossible to be a good person by human nature because we lie, blaspheme, steal, and lust. Jesus will supply hope, love, and grace in the most beautiful way and you will have certainty of heaven in His name.
