Confucianism isn’t a religion? So, what is religion? One definition from verywellmind.com states"
"Religion is a set of organized beliefs, practices, and systems that most often relate to belief and worship of a controlling force such as a personal god or another supernatural being. While this is a basic definition, there are many different understandings of what religion is and not all religions are centered on a belief in a god, gods, or supernatural forces. Religion often involves cultural beliefs, worldviews, texts, prophecies, revelations, and morals that have spiritual meaning to members of the particular faith, and it can encompass a range of practices including sermons, rituals, prayer, meditation, holy places, symbols, trances, and feasts."
So, the 5-6 million followers of Confucianism would likely disagree with your viewpoint.
"Buddhism requires works to reach nirvana." The concepts to reach Nirvana are below. I suppose for some, these are considered "work" but I'd say they really come down to simply living a good life and of being of good moral compass and actions.
- Refrain from taking life. Not killing any living being.
- Refrain from taking what is not given. Not stealing from anyone.
- Refrain from the misuse of the senses. Not having too much sensual pleasure.
- Refrain from wrong speech.
- Refrain from intoxicants that cloud the mind.
If all you need to do to get into heaven is admit you’re a sinner, ask for forgiveness, admit that Jesus died for your sins and rose again, and ask Him to have a relationship with you (not sure what kind of relationship), a deathbed conversion can hedge your bets. Or, are there rules on when one has to do all of the above before they die?
You have not answered the question posed:
If other religions do not believe in the concepts of heaven and hell as the Christian religion outlines it and do not do the above mentioned items, will Jesus send them to hell since they did not follow this guidance?
I'm simply curious if the ~6 billion non-Christians in the world are going to hell.
