The present tense represents a simple statement of fact or reality viewed as occurring in actual time. In most cases this corresponds directly with the English present tense.
Some phrases which might be rendered as past tense in English will often occur in the present tense in Greek. These are termed "historical presents," and such occurrences dramatize the event described as if the reader were there watching the event occur. Some English translations render such historical presents in the English past tense, while others permit the tense to remain in the present.
Word Voice
Middle or Passive Deponent
The middle or passive deponent forms in almost all cases are translated as being in the active voice.
The Greek infinitive mood in most cases corresponds to the English infinitive, which is basically the verb with "to" prefixed, as "to believe."
Like the English infinitive, the Greek infinitive can be used like a noun phrase ("It is better to live than to die"), as well as to reflect purpose or result ("This was done to fulfil what the prophet said").
