Prospective
This is the usage that most
grammarians would identify as central to the semantics and function of the
future tense form. In certain contextual environments the future form,
indicating expectation of intention, implicates future time reference in terms
of a prediction of events expected to take place. The notion of expectation
in the future is not dissimilar to projection, found in the subjunctive
and optative moods.
οὕτως ἐλεύσεται ὃν τρόπον ἐθεάσασθε αὐτὸν
πορευόμενον εἰς τὸν οὐρανόν. (Acts 1:11)
So he [Jesus] will come in the
same manner you saw him going into heaven.
τὸ θηρίον τὸ ἀναβαῖνον ἐκ τῆς ἀβύσσου
ποιήσει μετ᾽ αὐτῶν πόλεμον καὶ νικήσει αὐτοὺς καὶ ἀποκτενεῖ αὐτούς. (Rev. 11:7)
The beast that comes up out of the
abyss will make war with them and will overcome them and will
kill them. (David L. Mathewson, Voice and Mood: A Linguistic Approach [Essentials
of Biblical Greek Grammar; Grand Rapids, Mich.: Baker Academic, 2021], 133)
