Lukewarm Christian Question
I believe that God will not judge us if we are a Christian or not but he will judge us based on our heart. So its not absolute that if someone doesnt believe in religion/God doesnt mean they will automatically go to hell (because of environmental influence such as parents religion and the culture of their country, etc..). Lastly Religion/Churches should be only treated as Club thing(where fellow Christian should meet and interact to each other as well to God) not a space for performative act such as praying in churches even though they don't pray in their home and learn knew verses/word of God even though they surely know that they will never apply that in their live.
So what i want to say is that being in a religion and claiming you are a Christian just because you are active in church doesn't make you a Christian and that can be apply to the opposite as well where if you don't believe in a God/believe to other God doesn't mean your afterlife would be hell.
That's why its better to learn your theology first and find the most rational path before joining in any religion.
INC (Iglesia ni Cristo) - one of the most dominant Christian branch in Philippines where they believed that if you are not part of their religion then you will not receive salvation or be save.
