Next year, I'll convert into Judaism, then Islam, and Buddhism, then New Age....and Christianity back again.
Religion (I mean in general sense: words ending with -ism...) is, I think, like a pair of shoes.
I can wear Nike Air Jordan, Rebok Iverson stuff, or Addidas T-mac. Shoes don't make me a good ball player.
I mean, if I'm a good player, I'm a good player. There's nothing that can change that. Maker of shoe doesn't matter.
similarly, there's the salvation and there are religions, I think. Religions are like complementary addition to the salvation. You need a pair of shoes to play, but the shoes are not the game itself.
So, I think the salvation and religions are totally different things. Christianity doensn't save you. Neither Judaism or other religions.
What matters is whether you have the salvation or not, not which religion you're digging into.

Change your clothes, you'll be happy for a day.
Redo your hair, you'll be happy for a week.
Cahnge your religion, you'll be happy for two weeks.

But the problem is that the salvation is related to the faith of a particular religion. Ex, Judaism believes they have the covenant still valid. Chiristianity is based on the belief that a jewish guy Jesus kinda renewed the covenant so even Gentiles can have the salvation...

I don't know what I'm writing...Final is over and a good weekend is awaiting.
