Need to vent a moment. Recently, I have heard more people say the phrase "knock on wood" than I care to count. One person was carrying some boxes and "knock on wood" - he wouldn't drop them. Another was having an outdoor event and "knock on wood" - it wouldn't rain. AHHHHH!
Go ahead - knock on wood. See if it really helps.
I know my family tells me I over-spiritualize too much. But please, in an even exchange for the same number of words you could say "Jesus help me." And He would.
