The name of God in vain

I realise that one of the reasons why God doesn't like people to call His name in vain is because others may misunderstand and misintrepet who God really is.

It is the same as gossiping. Gossiping about a person will give the hearer an impression of the person that might not be totally accurate.

In the same way, God appears sometimes too scary, too slack, too insecure when we 'gossip' about Him

However, we still need to use the name of God. To answer our prayers and to discover more of His character. I believe only those who personally know God can do such a thing. Furthermore, the name of God does not become vain because it is said in full confidence of the trust that is in His name and character.
