“everything we do.” The Hebrew is more literally, “God will bring everything done into judgment.” Although the Hebrew lacks the personal pronoun, “we,” it is implied in the context. Leaving out the pronoun puts more emphasis on the short and punchy “everything done” so we understand that God will indeed judge everything, and not leave things out.

“every hidden thing.” Many things in life are hidden, some we are aware of and some people do without being consciously aware of them, but this certainly includes hidden motives.
