Just adding my 2 cents..
I am a new Christian. But my search for Truth (and of course I'm not done seeking) has brought me through the study of many religions, pseudo religions, occult practices, new age "stuff", spiritualism, Earth worship and all manners of what I know in my heart is nonsense.
The way to salvation is through Jesus Christ. There are a couple of cavats (sp?). Obviously repentance of your sins, as someone said before true repentance. And Faithfully and Truely knowing in your heart that although I am a wholly unworthy wretch Jesus shed his blood on the cross so that those of us who believe and accept His gift may be forgiven in the eyes of God. It's called Grace we are not even remotely close to be worthy of such a gift. But the other part of it is after you comit yourself to Jesus you need to work to walk like Jesus. Of course it's impossible to be perfect it doesn't mean you don't need to try.
I may be off base as I am new but that is what I had in my heart. Also this: VisaVis you are currently seeking and your taught to question and confront information you have problems with and that is wonderful. But that part of you that is missing that you are seeking is not actually a part of you. You can give me all the intellectual arguments you wish I've heard a great many of them. I've been on the giving end of such things as well but my head will never usurp my heart. Hopefully you will understand that.
Can people of all religions be saved: sure repent and give yourself to Jesus
don't matter what religion you currently belong to. The process of being saved is a Christian ( and IMHO) correct belief.
God Bless you all!
PS be gentle with me I am new and not as mature in the word as some of you are
