I am unaware of any in particular; however, “Providnece” has historically implied the guidance of the Deity. I would wager Obama was trying to have it both ways in leaving out “God” but inferencing Him.
Look at transcripts of Adolf Hitler’s statements in various conferences, particularly during the last year of the war and after the failed assassination attempt of July 20, 1944. He never makes reference to God, but always talks of how “Providence” was guiding his destiny.
It’s really, really creepy that 0bama would use the same term.
