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
No Tense or Voice Stated
In a number of places certain verbs are cited in Perschbacher's "The New Analytical Greek Lexicon" which do not have any tense or voice directly stated.
In almost all of these cases, one can assume that the tense is Present and the voice is Active, especially when the sense is that of a command (Imperative).
The indicative mood is a simple statement of fact. If an action really occurs or has occurred or will occur, it will be rendered in the indicative mood.
