| Strong's Number: 5735||Tense, Voice and Mood|
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.
The subjunctive mood is the mood of possibility and potentiality. The action described may or may not occur, depending upon circumstances. Conditional sentences of the third class ("ean" + the subjunctive) are all of this type, as well as many commands following conditional purpose clauses, such as those beginning with "hina."
