If Israel repents for even a single day, the Son of David (Messiah) will come immediately. If they do not repent, the redemption will come in its appointed time.
Rabbi Jacob said: This world (age) is like a lobby before the Age to Come; prepare yourself in the lobby so that you may enter the banquet hall… He used to say: Better is one hour of repentance and good deeds in this age than all the life of the Age to Come; and better is one hour of bliss in the Age to Come than all the life of this age.
Your dead will live; their corpses will rise. You who lie in the dust, awake and shout for joy, for your dew is as the dew of the dawn, and the land will give birth to the departed spirits. Come, my people, enter into your rooms [khedar, or wedding chamber], and close your doors behind you; hide for a little while until indignation runs its course. For behold, the LORD is about to come out from His place to punish the inhabitants of the earth for their iniquity; and the earth will reveal her bloodshed, and will no longer cover her slain.
Don’t let anyone deceive you at all! For the gathering will not come unless the apostasy comes first, and the man of lawlessness is revealed, the son of destruction, who replaces and exalts himself above every “god” or object of worship, so that he sits in the temple of God, displaying himself as being God.
