With  - (CW)  The Greek preposition translated as "with" has many meanings, many of which depend on the case of its object. With the dative, used here, the sense is static, "beside," "by the side of," "near," and "before." It can mean "with" but in the sense of "beside." "Aligned with" appears to be the sense here. This is not the common preposition translated as "with."

man -- (WN) The Greek word for "men" means "man", "person" and "humanity" in the singular. In the plural, it means "men", "people", and "peoples".  This word is not singular but plural.

is -- There is no verb "is" here in the Greek source but it is implied by the noun in the form of a subject having no verb associated with it.

impossible, --"Impossible" " is from an adjective that means "unable to do a thing", "without power," and "powerless." Of things, it means "impossible," and "unrealizable." It comes from the negative of the word means "having power."

but -- (CW) The Greek word translated as "but" denotes an exception or simple opposition. It is used to emphasize the contrast between things like we use "instead," "but instead,"or "rather." It is not the common word usually translated as "but." It is the Greek word "other" like we use "otherwise." Jesus almost always uses this conjunction to connect a negative clause, "not this," with a positive one, "instead this." However, here the conjunction is followed by the negative that give is the sense of "still" and  "at least."

not -- The Greek word translated as "not" is the Greek negative used to deny objective facts, not opinions. It makes a negative statement of fact. Adding "really" to the sentence captures the same idea.

God: The word translated as "God" means "God" and "deity." This is one of the rare times when there is no article with this word so "a god" or simply "God". Jesus usually used it with a definite article, but here he does not, at least not initially. Without the article, the sense is "a divine."

missing "because"  -- (MW) The untranslated word  MW - Missing Word -- The word "because" is not shown in the English translation."for" introduces a reason or explanation so "because" and, in questions, "why."
