The time period during which “this generation ” lives seems to correspond to the period covered by the first vision in the book of Revelation.
يَبْدُو أَنَّ ٱلْفَتْرَةَ ٱلزَّمَنِيَّةَ ٱلَّتِي يَعِيشُ خِلَالَهَا « هٰذَا ٱلْجِيلُ » تَتَطَابَقُ مَعَ ٱلْفَتْرَةِ ٱلَّتِي تُغَطِّيهَا أُولَى ٱلرُّؤَى فِي سِفْرِ ٱلرُّؤْيَا .‏
