Yet -- The Greek word translated as "but" denotes an exception or simple opposition. It is used to emphasize the contrast between things like we use "rather." It is the Greek word "other" like we use "otherwise." Jesus often uses this conjunction to connect a negative clause, not doing something, with a positive one, "instead do this."

coming  -- The word translated as "coming" primarily means "to start out" but Christ usually uses it to mean "come" but not always. It indicates movement, especially its beginning, without indicating a direction toward or away from anything, so it works either as "start," "come," or "go," but it is more like our phrase "being underway." Our English word "show up" captures both the "start" and "come" ideas. See this article for more.

will -- (WW) This helping verb "will " does not indicate the future tense, but that the verb describes a possibility, the subjunctive voice.

Helping verbs are not needed in Greek since the main verb carries this information in its form.
