Deuteronomy 32:18 (NIV) You deserted the Rock, who fathered you; you forgot the God who gave you birth.
Hosea 13:6 (NIV) When I fed them, they were satisfied; when they were satisfied, they became proud; then they forgot me.
Romans 1:21 (NIV) 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.
The careless soul is ever complaining, explains Scottish writer and preacher George MacDonald. "For the good that comes to him, he gives no thanks—who is there to thank? At the disappointments that befall him he grumbles—there must be someone to blame!"
—George MacDonald, Unspoken Sermons (Series Two).
