Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and His ways past finding out!—Romans 11:33
Webster's Unabridged Dictionary lists 550,000 words. And it is a solemn and beautiful thought that in our worship of God there sometimes rush up from the depths of our souls feelings that all this wealth of words is not sufficient to express. To be articulate at certain times we are compelled to fall back upon "Oh!" or "O!"—a primitive exclamatory sound that is hardly a word at all and that scarcely admits of a definition.
Vocabularies are formed by many minds over long periods and are capable of expressing whatever the mind is capable of entertaining. But when the heart, on its knees, moves into the awesome Presence and hears with fear and wonder things not lawful to utter, then the mind falls flat, and words, previously its faithful servants, become weak and totally incapable of telling what the heart hears and sees. In that awful moment the worshiper can only cry "Oh!" And that simple exclamation becomes more eloquent than learned speech and, I have no doubt, is dearer to God than any oratory.

"As a professional speaker, Lord, I'm trained to put my thoughts into articulate expression. But this morning I want to just quietly reflect in unspoken awe.... Amen."
