I -- The pronoun "I" is used here. Since, as the subject of the sentence, it is part of the verb, its explicit use accentuates who is speaking "I." Saying "I myself" captures this feeling in English.

missing "myself" -- (MW)  The subjective pronoun repeats the information in the verb so it should be repeated in English like "I myself."

missing "however"  -- (MW) The untranslated word "however" means "but," "however," and "on the other hand." It joins phrases in an adversarial way. Since it always falls in the second position, translating it as "however" often captures its feeling better.  It can also be an explanation of cause ("so").

am -- This helping verb indicates the present tense of the verb.

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.

seeking -- The Greek verb translated as "seek" has a variety of meanings around the idea of "searching" and "desiring." It has a sense of seeking with a specific aim.

missing "the"  -- (MW) The untranslated word is the Greek definite article,"the," which usually precedes a noun and, without a noun, takes the meaning of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those"). See this article for more. 

glory: -- (CW) The Greek noun translated as "glory" means "expectation," "notion," "opinion," "repute," and "popular repute." Translations as "glory" or "splendor" are found primarily in translating the Bible. The English words "acclaim" and "recognition" come closest to capturing the way Jesus uses the word. The verb form has the sense of "recognize."

for -- This word "of"  comes from the genitive case of the following word that requires the addition of a preposition in English.  The most common is the "of" of possession. However, it can also mean "belonging to," "part of," "which is," "than" (in comparisons), or  "for," "concerning" or "about" with transitive verbs.

myself; -- (CW)  "Myself" is the first-person possessive singular pronoun. This pronoun follows the noun so "of mine."  It is not the reflexive pronoun meaning "myself."

but -- (IW) There is nothing that can be translated as "but" here in the Greek source.

there -- This is from the third-person, singular form of the verb.

is -- The verb "is" here is the common form of "to be" in Greek. It means to have a certain characteristic or remain in a certain condition. It also equates terms or assigns characteristics.

one-- The word translated as "one" is the Greek definite article, without a noun, it has the sense of "the one." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more. 

who -- (IW) There is nothing that can be translated as "that" in the Greek source. It was added because the next verb was translated as active rather than as a participle.

seeks -- (WF) The Greek verb translated as "seeks" has a variety of meanings around the idea of "searching" and "desiring." It has a sense of seeking with a specific aim. This is a participle, not an active verb, "seeking."

and -- The Greek word translated as "and" is used as the conjunction "and," but it also is used to add emphasis ("also"). In a series, it is can be translated as "not only...but also." After words implying sameness "as."

he is the -- (IP) There is nothing that can be translated as "he is the" in the Greek source.

judge. -- (WF) The verb used here for "judge" means "judge," "criticize," "decide," "discriminate," and "separate," depending on the context. No English word corresponds to it precisely. It is often helpful to think of its primary meaning are the action of "to separate." This is a participle, not a noun, "judging."
