Well yeah i have an question about using our lord name

For example how much can we use Hevenly father word with (G)
to respect him because i learned that we shouldnt misuse his name for example its very bad to mention his name to much times or even saying he told me this and that and the words was full of arrogance right when someone use his name in anger rude attaking someone by that standard they sin correct?

Second i have a question about something else

Is it okay to use Lord or not because i saw in bible and in church we say Lord in bible many times it mentions Lord as well that s why i am confused is that okay when i have trouble or even Hevenly father and his name i can use when i feel that i am calm and with respect as well best to say in prayer to what s more better way

Do you think its sin to use lord instead his name because i see many times that use to not misuse his name for example even jews have been using it Lord is basically his name in hebrew Adonai
that  why i am confused

Imagine this story if someone tells you that he told me how this and that happened and use his name for our actions and action is from anger and saying all bad things offending your reputation then that doesnt come from him even if someone accuse you of having demons our Lord was also called names like that by pahrasies that s why i aded this story of example to ask what do you think?

The Second Commandment says to not take God's name in vain, it does not say we may not speak it at all. And there is an indulgence of 800 days each time the holy name of Jesus is said with reverence.

I agree that it is wrong to use God's name in vain, but there is no limit to how often we can speak of God properly.  I would expect that people who think about God a lot and who pray a lot also speak of Him a lot.  The mouth expresses what is in the heart.  

As a mother and grandmother, I am often in the situation of answering children's questions about God.  Or sometimes my husband likes to talk with me about things he has recently heard or read about religion.  These are just natural parts of my state of life in which it is good for me to speak of God.

To me this sounds like a Judaizing vestigate.  Jews even today often write G*d rather than the complete word.  So long as used reverently, there's no limit on invoking God.

In ancient times, there was this notion that invoking a god by name would give the invoker a certain authority over the god, and so the Jews tried to offset this tendency by never saying the name YAHWEH out loud (but replacing it instead with Adonai).  Now, part of it is that they misunderstood.  God, in giving His name, was essentially saying that He did not have a name, that he was not defined or circuмscribed by His essence (that could be named) but defined by His existence ("I am who am.")  So God cannot be "defined" or circuмscribed by any name ... nor, obviously, controlled by the invocation of a name.  Names define or limit things, designate something for what it is, but God is not anything, but merely is (existence without essence).
