Licking the Tin

I've been mulling over an expression in my mind. That expression is "licking the tin." Odd thing, huh? To me, it means to use all you've got, leaving nothing to waste. Licking the tin means foregoing dignity and even good manners to get every last ounce of nourishment. It's what I want... and I think it's what I am. I want to know God in every way possible. I want to grab all I can from Him and take it in, leaving my dignity and pride at the door and crawling to the altar of grace. I want to lick the tin.
