God knows

  1. Also, God only knows . Only God knows, that is, neither I nor anyone else knows, as in God knows where I've stored those photos , or God only knows how many people will join the march . [Second half of 1500s]

  2. Truly, certainly, definitely, as in God knows I need a winter coat . This expression, which originated about 1300 as God wot , does not necessarily imply that God is all-knowing but merely emphasizes the truth of the statement it accompanies.
