When someone approaches you in the Hebrew language and ask you the first question:
"What's your name?"
He is asking a question with a double meaning;
he also asks,
"What is your destiny?" (or) "What is your life propose?"
Since the word 'Name' (שם) have those two meaning.
More prosaically, this word has its primary understanding:
'Purpose (of life),'
and since we believe that God created each one of us,
so we put this purpose into a frame, and we call it a 'Name.'

This is what we started to explain this week
