Talking to God Without Saying a Word

I've long believed that the best prayers I've ever prayed were either wordless or nearly so.  Yet when I've expressed this to other people, even to other Christians, I don't recall ever getting an affirming response.  Maybe they think I'm saying that I pray without purpose, that I simply take some posture of prayer - kneeling, bowing, etc. - and remain silent without a specific aim in mind.  But that's not what I mean.  Rather, I mean when I'm afraid or hurt or anxious or ashamed or trying to make a decision where I don't like any option, many times the best I can do is to bow my head and groan or cry before the Lord.  I really don't know what to say and often don't know what to ask for.

Below is a quote from Charles Haddon Spurgeon's sermon, Paul's First Prayer.  It has greatly encouraged me concerning my wordless prayers.  He said:

"The poor broken-hearted sinner, climbing up to his chamber, bends his knee, but can only utter his wailing in the language of sighs and tears. Lo! That groan has made all the harps of heaven thrill with music; that tear has been caught by God, and put into the lachrymatory of heaven, to be perpetually preserved. The supplicant, whose fears prevent his words, will be well understood by the Most High. He may only shed one hasty tear; but "prayer is the falling of a tear." Tears are the diamonds of heaven; sighs are a part of the music of Jehovah's throne.”
