The predominant religion of the Vietnamese culture is Buddhism.  In other words they believe in reincarnation.  Also, the country of Vietnam recognizes Buddhism, Catholicism, Protestantism, Islam, Cao Dai, Hoa Hao.  However, ironically enough, the majority of the Vietnamese population claim to be non-religious.  

Buddhism is a false religion that has relied heavily upon a man.  This religion started with the worship of a man….I know this may be a shocking statement to some of you but, man can’t save you from the hand of an angry God.  I’m just saying!  STOP worshiping the creature more than the Creator…you’re going to make God angrier with you than He already is!

Romans 1:25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.

What you idol-worshipping, self-righteous, God-hating freaks need to understand is that whatever religion you claim to be or if you claim that you are not religious at all, you are all going to end up in the same place.  Hell is a very real place where the worm dieth not and the fire is NEVER quenched. 

Mark 9:48 Where their worm dieth not, and the fire is not quenched.

The laws of God are written on every man’s heart, therefore you know there is only one God and you know how to worship Him.  You are a stubborn and rebellious people who REFUSE to give God the glory which is why you have had such a treacherous past and your future looks so dire.
 
James 2:19 Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
