Knowing name is important ???

I met a few people today and they said that God has a name and that it is important just as my name is impotant. I thought to myself "God has a name and that it is important?" They said that by knowing God's personal name, we may have life through it.

I said that it is not neccesarry for me that God has a more personal name than father or Lord. But they insist that God's name is important so i said " alrighht then if u wanna think that way but for me it is not as important and that what give me life is not the name but the cross."
I also insist that by calling God Lord or father, it is personal already so having the more personal name is not neccessary.I couldnt explain my reason properly to them :(:( oh well next time maybe if i bump into them again?? ;);)

As the day goes by, i thought through my reasons and making it clear in my head so then when i bump into them again, i would be able to explain it better :D:D

• Name is important as it is useful to differentiate one person and another. There would be noone who would call himself/herself God right?? so the more personal name of God is not important as there is one God anyway. Not like we need a more personal name for Jessica because there are many Jessicas out there (sorry for those whose name are Jessica) :D:D
• The people that i met insist that it is important to know God's personal name because it can gives us salvation. Does salvation comes from knowing his name or from the cross?? I think that salvation comes from the cross because without the cross we wouldn't know God and wouldn't even bother to know him. The cross is how i can call God father and he call me children. Hence, the cross is the centre not the name!
