Ok... without getting all Theo-logic on ya.. an excerpt from the Bible which describes manna... God provided and yet they/we still complained... our nature? hmmm

Numbers 11:7-15 (New King James Version)

7 Now the manna was like coriander seed, and its color like the color of bdellium. 8 The people went about and gathered it, ground it on millstones or beat it in the mortar, cooked it in pans, and made cakes of it; and its taste was like the taste of pastry prepared with oil. 9 And when the dew fell on the camp in the night, the manna fell on it.

Good stuff Skip... keep'em comin'! :)
