So true.. I know personally of several people that found Christ with no preaching or preacher and had never even heard the name or known the concept of a "Christ"(Messiah).. yet when they called out to God.. they got a revelation of the Christ.. Not some human acting like Christ but the real one.. If Jesus were named Charlie nothing would change.. Cause its not in the name its in the person.. The name Jesus stands for something so does Yeshua which was his real name but even Yeshua can't contain the one that should not be named..
Thats as it should be since Jesus name is not Jesus anyway.. and Jehovas name is not Jehova... Hebrew has no "J's"... Any that think this God can be limited to a name don't know him yet.. or their growth spiritually has been stunted or is incomplete..
This God replied to Moses when asked for a name, Tell Them, "I am that I am", sent you... denying Moses a name.. Asking for Gods business card is bit arrogant.. The Jews had to make up a name.. They were not given one.. The so-called Gods of this earth NEED a name.. the real God does not..
Conversations with these people that found Christ was an important day to me.. it strengthened my faith.. It proved to me that this God and this Christ were closer TO ME than my very self.. And my daily activitys and relationship to this one was being watched... and graded for reality content..
As this God told me personally, I believe, "I will as real to you, as you are with me"... Don't know if thats the deal with everybody, but it sure is with me.. And he is.. Praying to some Universal Superhero (like a Greek God) don't get it for me.. I need a person or personality.. and he is..
Maybe sometime if the situation is right I can share some of what those people that found God on their own shared with me.. maybe not.. All I have is my own experience and share that.. for that is what fellowship is.. And part of what we do here is fellowship about who and what we are devoted to..
Some might find Romans 1 and 2 a great meditation for the points you have raised about those who never knew His name.
Concerning "what's in a name" though, I'd like to point out that some Jewish mysticism asserts that a name is a description or revelation of a person. Thus, the Father has many names and they see the Torah as another name for Him. Also, in John 17 - Jesus speaks of declaring the Father's name and Jesus Himself has a name above every other name and one known only to Himself (Revelation, etc.)
