"Your kindness and your truth always will guard me." (Shacharis Prayer)
Tamid (always) means without a pause, for if His kindness and His truth should for a moment be interrupted, noone could exist. A man's existence (and the existence of the entire Universe) is solely due to G-d's kindness and truth which stands guard over him. When some mishap occurs, its purpose is to remind him of the hundreds of thousands of other times that Hashem's kindness stood guard over him incessantly. -- Praise, My Soul.
