You want to talk religion, than you are asking for the projections of others. Because it's a rare person that will sacrifice their beliefs, even just for common courtesy. If your goal is to spread your faith, I would suggest targeting those who are open to it. There's a lot of people out there who are like an open book, with some blank pages. If you just like to argue for the sake of arguing, that's cool too. But I like to think I'm above most of all that.
As far as repentance goes my worldview tells me it's a completely pointless endeavor. Christ's only real purpose on Earth was to teach the "Gnosis". Anything else is irrelevant. The idea of Sin to me, is simply a social construct. It's just stuff people were taught growing up. Like we could completely remove the idea of Sin without affecting the moral compass of the world. This tells me the idea isn't Godly, but man made.
Ascension can only be achieved through the "Gnosis". The goal is to leave this physical world behind. You have to be immaterial, or you simply cannot be saved. All the repentance and prayer in the world wont make one bit of difference if your true love is money, and things of the physical world. You can't be half of a spiritual person, you need to be wholly spiritual.
