When I pray, I sound like I'm talking to an old friend. Yet God still understands me with my "ums" and "you knows" and other non-polished words that I use.
Jesus does help us out and gives us some guidelines - mostly because some people were praying just to hear themselves talk. He says this (from The Message):
Our Father in heaven,
Reveal who you are.
Set the world right;
Do what’s best—
as above, so below.
Keep us alive with three square meals.
Keep us forgiven with you and forgiving others.
Keep us safe from ourselves and the Devil.
You’re in charge!
You can do anything you want!
You’re ablaze in beauty!
Yes. Yes. Yes.
So I can't give you a formula or advice. All I can say is pray simply. And pray often.
Until Everyone Hears,
