You're my God my King

Do words like "Lord" and "King" work in the context of God when we use them these days?
Expressing what God really is (worth-wise) is a bit of a tricky one anyway, saying "God is awesome" just doesnt really express enough how truly magnificent He is, none of our words really can, even if you decide on the best word to express infinite magnificence you could still call a human that so God is a ridiculous amount above that. So i guess back in the day calling God your Lord or King made sense, a person who rules over you and ultimately decides how you live your life, its not a bad description really. But does it work in 2008? The term King to me denotes an unelected scrounger whose status exists because the masses choose not to revolt against him, someone whose income depends on the masses, performs services to the country (shakes hands of important people of other countries) but ultimately has hardly any authority or power (unless we are talking about killing swans or getting people out of prison) and is not overly well liked. The word Lord makes me think of a fat posh toff who has been given this role either through inheritance or under the table bribes. I guess that might just be because im British though, would it mean anything at all to me if i was American? So using the words Lord or King to mean God dont really say what im wanting them to say. Apparently the word "Lord" comes from an old english word meaning "bread keeper", back from the old custom of a superior providing food for his followers (thanks Wikipedia), that seems more like what i mean. How has the word changed so much in meaning from what it used to be?
