2. It is absolutely true, certain, or definite that; it is obvious or clear that. God knows I need to do well on this test or I can kiss my scholarship goodbye!
Also, goodness knows; heaven knows.
1. 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. The variants using goodness and heaven are euphemisms that avoid taking God's name in vain. [Second half of 1500s]
2. 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]
1 I do not know; no one knows: ‘What’s going to happen next?’ ‘God knows.’
2 used for adding emphasis to a statement, opinion, etc: God knows how he manages to survive on such a small salary. ♢ I’m no gardening expert, goodness knows!(Some people may find the use of God knows offensive.)
