"I will refuse nothing that you ask of me"

Question

Is the expression "I will refuse nothing that you ask of me" equivalent to saying "I will do everything that you ask of me" in a strict sense?

Thank you,

Answer 1

There is a tiny difference.

The first says the speaker will not "refuse", but does not explicitly state that he will "do" what is asked. This gives a tiny bit of wiggle room to not fulfill a request which is "impossible".

But that would be "lawyer's" interpretation, not the "man-on-the-street" one, and the "man-on-the-street" reading would be that the first is the same as the second only more dramatic.

Answer 2

Yes. They both indicate that everything is a possible request and that nothing is an impossible request. The first may be a bit more dramatic.
