On-screen directions in UI: telling users to do the obvious

Should we include directions to a user in the UI content that tells them to do something that is visually obvious?

For example, we inform users that they need to verify their device. Text includes "Click Verify to get started," where there is a button below with the word Verify on it.

In favor of the text: including the obvious instruction makes the UI content more accessible, as a screen reader picks up the "Click Verify..." text so that a non-sighted user knows what to do.

Others say that the design should be so intuitive that no directions are needed.

Any standards out there that should apply?
