Observe, too, that the parable confirms the idea of a process having stages, for the lesson of the blossoming fig-tree is not that summer has come, but that it is nigh.
The solemn assurance in verse 32, made more weighty by the 'Verily I say,' seems at first sight to bring the final judgment within the lifetime of the generation of the hearers. But it is noteworthy that the expression 'till all things are fulfilled' is almost verbally identical with that in verse 22, which refers only to the destruction of Jerusalem, and is therefore most naturally interpreted as having the same restricted application here. The difference between the two phrases is significant, since in the former the certainty of fulfilment is deduced from the fact of 'the things' being written--that is, they must be accomplished because they have been foretold in Scripture,--whereas in the latter Christ rests the certainty of fulfilment on His own word. That majestic assurance in verse 33 comes well from His lips, and makes claim that His word shall outlast the whole present material order, and be fulfilled in every detail. Think of a mere man saying that!
IV. Exhortations corresponding to the predictions follow. Christ's revelation of the future was neither meant to gratify idle curiosity nor to supply a timetable in advance, but to minister encouragement and to lead to watchfulness. Whether 'that day' (ver. 34) is understood of the fall of Jerusalem or of the final coming of the Lord, it will come 'as a snare' upon men who are absorbed with the earth which they inhabit. They will be captured by it, as a covey of birds in a field busily picking up grain, are netted by one sudden fling of the fowler's net. A wary eye would have saved them.
The exhortation is as applicable to us, for, whatever are our views about unfulfilled prophecy, death comes to us all at a time which we know not, as the Book of Ecclesiastes, using the same figure, says; 'Man knoweth not his time ... as the birds that are caught in the snare.' Hearts must be kept above the grosser satisfactions of sense and the less gross cares of life, being neither stupefied with gorging earth's good, nor preoccupied with its gnawing anxieties, both of which are destructive of the clear realisation of the certain future. We are to preserve an attitude of wakefulness and of expectancy, and, as the sure way to it, and to clearing our hearts of perishable delights and shortsighted, self-consuming cares, we are to keep them in a continual posture of supplication. If our study of unfulfilled prophecy does that for us, it will have done what Jesus means it to do; if it does not it matters little what theories about its chronology we may adopt.
The two stages which we have tried to point out in this passage are clearly marked at the close, where escaping 'all these things that shall come to pass' and standing 'before the Son of man' are distinguished. True, both stages were to be included in the experience of Christ's hearers, but they are none the less separate stages.
Luke's version of this great discourse gives less prominence to the final coming than does Matthew's, and does not blend the two stages so inextricably together; but it gives no hint of the duration of the 'times of the Gentiles,' and might well leave the impression that these were brief. Now in this close setting together of a nearer and a much more remote future, with little prominence given to the interval between, our Lord is but bringing His prophecy into line with the constant manner of the older prophets. They and He paint the future in perspective, and the distance, seen behind the foreground, seems nearer than it really is. The spectator does not know how many weary miles have to be traversed before the distant blue hills are to be reached, nor what deep gorges lie between.
