@Scribble: I do believe that good works naturally flow from people who've been truly saved but the works themselves are not what saves you. Earning your way to Heaven thru works is not what scripture teaches. (at least not if you're reading the actual HOLY Bible aka The King James version which is hopefully what u r reading). People who're truly saved WANT to do good works because they know that it is the right thing to do, not because they think it'll earn God's approval.
They know that Christ's sacrifice on the cross fully paid the price for our sins (both future and past). The danger with believing in a works salvation or even faith + works is that you can easily become filled with pride over it and God hates that.
You should put your faith in Jesus Christ alone. Anything else and you're basically thinking that Christ's sacrifice wasn't enough. The Bible (again, this is if u r reading a KJV, not sure about the other versions but I wouldn"t trust them if I were you) says that Salvation is a free gift to those who truly want it. Of course, like any gift, you are free to turn it down if you like but if you genuinely accept it then you are forever saved. Nothing you do, no matter how bad, will ever make you lose your salvation. You will find that this will give you lasting peace of mind. You will still want to do good works but it will then be for the right reasons, not because you think it'll save you.
Remember, it is a free gift. If it was hard or you had to work for it then it wouldn't truly be a gift would it? When someone gives you something and they expect something in return it's not really a gift is it?
At least you're actually reading your Bible pretty regularly though. I salute you for that. That is something I need to get in habit of doing a lot more often. Get so caught up in worldly things that I never get around to making time for it. Usually the only time I really get around to reading it is when I'm sitting on the toilet lol. And even then, usually only read about one chapter. At this rate, Judgment Day will be here long before I finish.
It's just that some books have such incredibly boring parts it makes me want to sleep. Trying to read the book of Numbers currently. Jesus, it's so boring... not like Genesis, Exodus, or any of the Gospels or, of course, Revelation. Loved all those. Leviticus had a lot of really boring parts as well.
Oh yeah, in regards to your part about you not believing serial killers are saved just by believing: why not? Anyone who is genuinely sincere in asking God for forgiveness can be saved. Of course I'm not saying they don't deserve the death penalty for murdering someone in cold blood and I'm all for the death penalty 100%. But in regards to their eternal salvation then yes, I absolutely believe they can be saved if they're truly sincere in asking forgiveness. Saved from Hellfire, not saved from being punished by man for killing another innocent human being.
