Of course the future is not settled. If the future is settled then the kingdom will not be "at hand" or "nigh at hand" until the Lord Jesus returns to the earth:
"And then shall they see the Son of man coming in a cloud with power and great glory. And when these things begin to come to pass, then look up, and lift up your heads; for your redemption draweth nigh. And he spake to them a parable; Behold the fig tree, and all the trees; When they now shoot forth, ye see and know of your own selves that summer is now nigh at hand. So likewise ye, when ye see these things come to pass, know ye that the kingdom of God is nigh at hand (eggys)" (Lk.21:27-31).
Here the words "nigh at hand" are translated from the Greek word
eggys and that word means
"of times imminent and soon to come pass" (
Thayer's Greek English Lexicon).
If the future is settled and everything is set in stone then it would be impossible that the Lord Jesus would have told the Jews that the kingdom was at hand in the first century because it cannot possibly be "at hand" until the Lord Jesus returns to the earth. But that is exactly what He told them:
"From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand (eggizō)" (Mt.4:17).
Here the words "at hand" are translated from the Greek word
eggizō, and that word means "
to be imminent"
(A Greek English Lexicon, Liddell & Scott [Oxford: Clarendon Press, 1940], 467).
In a note in
The Scofield Study Bible we read that
"the Biblical term 'at hand' or 'near' is never a positive affirmation that the person or thing said to be at hand will immediately appear, but only that that person or thing has the quality of imminency" (Note at Matthew 4:17).
Something that has the quality of imminency is something that could possibly happen at any moment.
Since the Lord Jesus thought that the kingdom could be brought in during the time when He walked the earth then that means that He did not think the future is settled, that the kingdom could not possibly be at hand until He returns.
So from what the Lord Jesus said at Matthew 4:17 it is clear that the future is open!
