To God, a thousand years is as a day (1 Peter 3:8). In light of that, consider this: 1) It has been exactly 2,000 years since last we saw Christ here on earth, and 2) Christ's delay after the death of Lazarus and prior to his resurrections was two days. I see a metaphor here suggesting that the two-thousand years of mortality and mourning transpiring since the resurrection of Christ is but a brief prelude to the joys of life from among the "dead."
