as true as I stand here

old-fashioned Used to assert or emphasize that what one is saying is completely true. It's as true as I stand here—if I'd have known you had feelings for Miss Kensington, I never would have asked her to accompany me to the gala. I assure you, as true as I stand here, that I did not take that money. I wasn't trying to undermine you. I didn't even know you'd applied for the same job, as true as I stand here!
