Philippians 2:15 (YLT) that ye may become blameless and harmless, children of God, unblemished in the midst of a generation(genea) crooked and perverse, among whom ye do appear as luminaries in the world,
I have suggested this before, maybe not in this thread though, this is the generation Jesus could be meaning in the OD, the one recorded in .Philippians 2:15 above.
Matthew 24:34 Verily I say unto you, This generation shall not pass, till all these things be fulfilled.
IOW---Verily I say unto you, This crooked and perverse generation shall not pass, till all these things be fulfilled.
Matthew 24:35 Heaven and earth shall pass away, but my words shall not pass away.
36 But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
2 Peter 3:7 But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
2 Peter 3:10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
2 Peter 3:13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
Thus, something along the lines per the following.
the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men---this crooked and perverse generation shall not pass away, till all be fulfilled---Heaven and earth shall pass away, but of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.---the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up---Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
