No-- (WW) The word translated as "for" introduces a reason or explanation so "because" and, in questions, "why." However, since this word always appears in the second position, it is more like an aside remark like, "consequently" or "as a cause."

the -- The word translated as "the" is the Greek definite article. When not preceding a noun, takes the meaning of "the one" or, in the plural, "the ones." The Greek article is much closer to our demonstrative pronouns ("this," "that," "these," "those") than the English "the." See this article for more. 

Father -- "Father" is the Greek noun that means "father" or any male ancestor so "forefathers." It is the word that Christ uses to address his own Father.

himself -- The word translated as "he" is the Greek word commonly translated as third-person pronouns in English.  When the subject of the sentence is part of the verb, the pronoun's explicit use accentuates who is acting "He." Saying "he himself" captures this feeling in English.

loves  -- (CW)  "They love" is one of two Greek words that are translated as "love" but mean different things. The verb expresses a preference or a liking for something or someone.  Its meaning is more like "enjoy" than "love" in English. More on the two types of "love" in this article.

you, -- The "you" here is the second-person, plural pronoun in the form of an object of the action or preposition.

because-- The word translated as "that" introduces a statement of fact or cause, "for what," "because," "since," and "wherefore."

you -- The pronoun "you" is used explicitly as the subject of the sentence. When it has no verb, the verb "is" or the previous verb is assumed. When it is already part of the verb, its use here creates emphasis on the "you" as we might say "you yourselves." It is plural.

missing "yourselves"  ---- (MW) The pronoun is used here explicitly as the subject of the sentence. Since this information is already in the verb, the sense is repetitive as we say "you yourselves." 

have -- This helping verb "have" indicates that the verb is the tense indicating an action completed in the past.

loved -- (CW)  "They love" is one of two Greek words that are translated as "love" but mean different things. The verb expresses a preference or a liking for something or someone.  Its meaning is more like "enjoy" than "love" in English. More on the two types of "love" in this article.

me,-- "Me" is the regular first-person pronoun in Greek as the object of the verb or preposition. As the object of a preposition, an accusative object indicates movement towards something or a position reached as a result of that movement.

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 can be translated as "not only...but also." After words implying sameness "as."

have -- This helping verb "have" indicates that the verb is the tense indicating an action completed in the past.

 and have believed that I came from God.

believed -- (CW) The Greek word translated as "believed" does not apply to religious belief as much but trusting or relying upon other people, especially their words. Jesus usually uses it in contexts, such as the one here, that apply to trusting words.

that -- (CW)  The word translated as "that" introduces a statement of fact or cause, "for what," "because," "since," and "wherefore." This word was translated as "because" above.

I -- The pronoun "I" is used here.  When it has no verb, the verb "is" or the previous verb is assumed. When the subject of the sentence 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 subject pronoun repeats the information in the verb so it should be repeated in English like "I myself."

came -- The word translated as "ye go thence" means literally "to go or come out," but it has a secondary meaning of "making something come true."

out -- This is from the prefix of the previous verb that means "out."

from -- The Greek preposition translated as "from" has many meanings, many of which depend on the case of its object. With the genitive, the sense is motion, "from the side of," "from beside," and generally "from." With the dative, the sense is static, "by the side of," "near," and "before." With the accusative, its has a number of specialized meanings depending on the character of the verb, with coming/going "near," "beside," with placing "side-by-side," as a metaphor, "like" or "as a parody of, of comparison, "compared with" and many more.

God. -- (OS) There is nothing in the Greek that can be translated as "God" in the source we use today but it does exist in the source that the KJV translators used. In my source (and that used by more recent Bibles) the word is "father." This is also more consistent with what Jesus has been saying before this.

missing "the/this"  -- (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," and "those"). See this article for more. 

missing "Father"  -- (OS) The untranslated word   "father" or any male ancestor so "forefathers." It is the word that Christ uses to address his own Father. It does exist in the source that the KJV translators used.
