Neither. You aren't changing those versions. You are changing the English version (specifically the NIV translation that you were quoting from).
Yes, it is.
There are theological disagreements about what's required for salvation. Some say all you have to do is believe. Some say that you have "act" like a Christian. Some people believe there is a literal hell that people are sent to (per New Testament) and other people don't believe that (per the Old Testament). I could go on and on.
All sorts of churches teach all sorts of different things, but as ITN already mentioned, a church is not the authoritative reference of The Bible. The Bible itself is the authoritative reference of The Bible.
Yes, different churches will teach different things about what is required for salvation. However, The Bible itself makes it very clear that salvation is the result of God's grace through faith alone. (Source: Ephesians 2:8-9)
Even the most skeptical of people will have faith in many different things, such as having faith that a chair won't break when they sit down in it. In fact, life in general is a constant series of acts of faith, with some acts of faith being greater than others. Accepting the finished work of our LORD and Savior Jesus Christ (his death and resurrection) is the ultimate act of faith.
One cannot earn one's way into Heaven. The only way there is via the gift of God's grace, through faith alone. How does one receive this gift? One receives this gift in the very same manner as one receives any other gift. One reaches out and receives the gift unto oneself. For a $100 bill, it means reaching out one's hands and receiving the $100 bill in one's grasp. For the gift of salvation, it means reaching out to God in prayer and receiving his gift of salvation (receiving his gift of eternal life through Jesus Christ).
As for "a literal hell" or not (you need to be more specific with that word, but I do know what one is typically referring to whenever the word 'hell' is used), The Bible is VERY clear about the existence of what is described as a "lake of fire" (Source: Revelation 20:14). This passage says that both 'death' and 'hell' (aka hades) will eventually be thrown into this aforementioned "lake of fire" (aka the second death, aka the eternal death). At this point, those who have "life" (through Jesus) and those who have "death" (without Jesus) are eternally separated from each other.
You're conflating "not agreeing with you" with "not familiar with the Bible".
Nope. Your issue is that you are relying on the (lack of) intellect of your mind masters rather than spending time with The Word for yourself. Just as you need to spend time with a person in order to get to know him or her better, you also need to spend time with The Word in order to get to know HIM better.
I do understand them as they are written. You want to interpret them differently. Again, if the Bible were clear....
Nope. At this point, you don't know The Word at all. That truth is self evident.
Yes, you've explained your interpretation of them. I've explained my interpretation of them. Remember when I said there's no point in continuing the discussion because we aren't going to agree. I continue to be right.
Nope. At this point, you continue to be clueless. You continue to refuse to learn. You continue to refuse to spend time with The Word.
