The immanence language saturating the New Testament was not rhetorical urgency meant to be stretched across millennia, but covenantal nearness grounded in the Day of Atonement pattern that framed how first-century Jews understood atonement, mediation, and divine verdict.
Under the old covenant, the high priest entered the Most Holy Place with blood and the people waited outside, and the sign that the sacrifice had been accepted was the priest’s re-emergence from the tabernacle; the atonement was publicly confirmed when the mediator came back out alive (Lev. 16), which is precisely the pattern Hebrews applies to Christ when it says, “The Holy Spirit indicates that the way into the holy places is not yet opened as long as the first section is still standing” (Hebrews 9:8) and then, “so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him” (Hebrews 9:28)—the logic is not that Christ will be re-sacrificed, but that His re-appearance functions as the covenantal confirmation that the atonement has been accepted and the old order has been judged.
This is why the apostles speak with unembarrassed imminence, not in vague devotional language but in time-bound covenantal expectation, because they were living in the overlap of the ages where the High Priest had already entered the true sanctuary “not made with hands,” yet the public verdict on the old temple order had not yet fallen, which is why Hebrews can say without qualification, “For yet in a very little while, he who is coming will come and will not delay” (Hebrews 10:37); the “Day of the Lord” anticipated throughout the New Testament is therefore not a postponed global spectacle but the historical moment when God rendered His verdict on the old sanctuary and priesthood, vindicating the once-for-all atonement of Christ by tearing down the house that claimed it was still needed, so that the destruction of Jerusalem in AD 70 functioned as the covenantal “coming out” of the High Priest from the tabernacle not made by hands, the visible confirmation in history that the sacrifice had been accepted, the old age had passed, and the new covenant order was no longer approaching but had fully arrived.
