The Bible is very clear through multitudinous Scriptures to the fact that God requires GRATEFULNESS. We are to give thanks in all things---good and bad---if we believe that God is sovereign and working through them all (Rom. 8:28). The failure to do that is one of the characteristics of those who have fallen from the working of the grace of God in their lives, and is noted in Romans 1: "For although they knew God, they neither glorified Him as God NOR GAVE THANKS to Him, but their thinking became futile, and their foolish hearts were darkened." (Rom. 1:21)
Mark Twain said, "You can take in a stray dog, feed him and cause him to prosper, and he will not bite you. This is the fundamental difference between men and dogs."
