To attribute the coming of Titus in AD70 in 1 Peter 4:3-7 as the "end of all things" is laughable, unbiblical and irrational. It states: “the time past of our life may suffice us to have wrought the will of the Gentiles, when we walked in lasciviousness, lusts, excess of wine, revellings, banquetings, and abominable idolatries: Wherein they think it strange that ye run not with them to the same excess of riot, speaking evil of you: Who shall give account to Him that is ready to judge the quick and the dead. For for this cause was the gospel preached also to them that are dead, that they might be judged according to men in the flesh, but live according to God in the spirit. But the end of all things is at hand.”
Peter continues in verse 13 of the same passage, whilst speaking of that great final event, by encouraging the believers, saying, “rejoice, inasmuch as ye are partakers of Christ's sufferings; that, when his glory shall be revealed, ye may be glad also with exceeding joy.”
As Eric said, the coming of Christ and the end of all things is near to God since He is not limited to time. What is more, what is considered near to Him can seem like a long time to us.
Peter informs us that “end of all things” occurs at the Second Advent – the time when Christ shall judge “the quick and the dead” (or the living and the dead). Moreover, he indicates, whilst the day of revelation of Christ is an awful day of woe for the wicked, it is a day of joy and reward for the righteous. Notwithstanding, and significantly, the judgment of the wicked and “the end of ALL things” is said to be “at hand” or ‘eengiken’ meaning ‘to be near’ or ‘approaching.’ Notably, it is from the usage of this word that the Pretribbers argue for an imminent secret return of Christ rather than an impending all-consummating final return, as is biblical. Notwithstanding, whether one understands the term “at hand” as imminent or impending isn’t particularly important here, it is the fact that the judgment of the wicked coincides with the one final future all-consummating Second Advent. Also, the clear allusion of the judgment of “the living and the dead” unquestionably proves a general judgment as the A and Postmillennialists believes.
The second coming is all-consummating and ushers in the complete end of all things old, temporal, sinful and corrupt. His return introduces the beginning of all things new, eternal, righteous and God-glorifying.
In the new heavens and new earth there is going to be no more grief, grave stones or goodbyes. There is coming a day in the future when dying, crying, pain, sorrow and the curse will cease. Or put differently, there is going to be no sea, no sepulchers, no sorrow, no suffering. All the awful effects of sin have finally and eternally been expunged, namely death, disease, disaster, disappointment, depression, and despair. All things are now new.
