I’ve been wanting to share quotes from Martin Luther’s commentary on Gen 48:20 (Heb 11:21), as they pertain to much of what has been said here, but they only make sense in their full context. So here it is: Luther – Genesis 48:20. In a nutshell – he glories in the Church. Spiritual blessing/promises are far more glorious than temporal blessing/promises, and our Lord has only promised us slender temporal blessings which ought to be enough for us (Matt 6:32-33). Luther is no silver bullet to solving eschatological (really, philosophy of history) debates, but he gives food for thought, and boy does he ignite your love for the Church and the Word. This man’s faith was so full of holy violence (Matt 11:12). (Fair warning for credo-baptist brothers: you won’t like what he says about baptizing infants 
. And yes, he does sound sacerdotal, but no, he is not)
As for millenarianism, came across this from the Catechism of the [Roman] Catholic Church (no, I’m not converting, and neither should anyone):
The Church’s ultimate trial
675 Before Christ’s second coming the Church must pass through a final trial that will shake the faith of many believers. The persecution that accompanies her pilgrimage on earth will unveil the “mystery of iniquity” in the form of a religious deception offering men an apparent solution to their problems at the price of apostasy from the truth. The supreme religious deception is that of the Antichrist, a pseudo-messianism by which man glorifies him self in place of God and of his Messiah come in the flesh.676 The Antichrist’s deception already begins to take shape in the world every time the claim is made to realize within history that messianic hope which can only be realized beyond history through the eschatalogical judgment. The Church has rejected even modified forms of this falsification of the kingdom to come under the name of millenarianism, especially the “intrinsically perverse” political form of a secular messianism.
677 The Church will enter the glory of the kingdom only through this final Passover, when she will follow her Lord in his death and Resurrection. The kingdom will be fulfilled, then, not by a historic triumph of the Church through a progressive ascendancy, but only by God’s victory over the final unleashing of evil, which will cause his Bride to come down from heaven. God’s triumph over the revolt of evil will take the form of the Last Judgment after the final cosmic upheaval of this passing world.
