can- - (WF) The word translated as "can" means having the power or possibly a desire to accomplish something. Often, in English, "can" is a helper verb, indicating a possibility. In Greek, it indicates ability or power. This is the active verb here, not a helper verb. It takes an infinitive as "have the ability" does in English.

-not -- The Greek word translated as "not" is the Greek negative used to deny objective facts, not opinions. It means "no," "not," or"no truly." It makes a negative statement of fact. Adding "really" to the sentence captures the same idea. When a negative precedes the verb, it affects the whole clause. When it precedes other words, its force is limited to those words.

come. -- (WF) The word translated as "come" 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. It is an infinitive, not an active verb, "to show up."
