Jesus' prophecy about the destruction of the city and the Temple, sometimes called the Little Apocalypse, causes bewilderment among many. This bewilderment first arose in the second generation of Christians, some of whom lived to the year 70 and saw with their own eyes the devastation of Jerusalem and the destruction of the Temple of which the Saviour speaks. This was because what Jesus had predicted happened, while He Himself still did not return. Another revelation, given to the apostle John, was needed before the meaning of the new era became clearer. Jesus Himself, meanwhile, seems not to have gone into detail when speaking about the end times and His return in glory. He mentions only the principal events: the end of the former age and the coming of the Kingdom in all its fullness.
The revelation received by John completed the picture: it portrays an entire age, the age of the advancing Kingdom, which the Saviour does not mention at all in His prophecy. This is understandable, however: He was telling the disciples about the coming events when history had not yet ended, when the Temple was still standing in its place. In Jesus' words, it is precisely the end of the Second Temple that becomes the end of times.
This might seem strange: almost two thousand years have passed since the year 70, yet history apparently continues. But from the standpoint of the processes that began with Christ's coming into the world, the former history really did end with the end of the Second Temple. All subsequent events belong to another age, one wholly defined by the moment of its completion and therefore by the Saviour's return and the manifestation of the Kingdom to the world in all its fullness. This is precisely why, immediately after describing the devastation of Jerusalem and the Temple, Jesus turns to the subject of His return and the triumph of the Kingdom. He says nothing about the transitional age itself. This is why those who remembered this conversation formed the impression that Jesus would return immediately, or almost immediately, after these events.
The revelation received by John after the year 70 put everything in its place: it became clear that an entire age was meant, the age of the advancing Kingdom in which we too have had to live. Yet it can already be regarded as the home stretch leading us to the goal. The main thing is to reach it.

3:16 All scripture is inspired of God - The Spirit of God not only once inspired those who wrote it, but continually inspires, supernaturally assists, those that read it with earnest prayer. Hence it is so profitable for doctrine, for instruction of the ignorant, for the reproof or conviction of them that are in error or sin, for the correction or amendment of whatever is amiss, and for instructing or training up the children of God in all righteousness.
3:17 That the man of God - He that is united to and approved of God. May be perfect - Blameless himself, and throughly furnished - By the scripture, either to teach, reprove, correct, or train up others.

4:1 I charge thee therefore - This is deduced from the whole preceding chapter. At his appearing and his kingdom - That is, at his appearing in the kingdom of glory.
4:2 Be instant - Insist on, urge these things in season, out of season - That is, continually, at all times and places. It might be translated, with and without opportunity - Not only when a fair occasion is given: even when there is none, one must be made.
4:3 For they will heap up teachers - Therefore thou hast need of "all longsuffering." According to their own desires - Smooth as they can wish. Having itching ears - Fond of noveltyand variety, which the number of new teachers, as well as their empty, soft, or philosophical discourses, pleased. Such teachers, and such hearers, seldom are much concerned with what is strict or to the purpose. Heap to themselves - Not enduring sound doctrine, they will reject the sound preachers, and gather together all that suit their own taste. Probably they send out one another as teachers, and so are never at a loss for numbers.
