The end of history
Put simply, the Christian story unravels unless God brings the entire course of human history under His visible and perfect judgment, unless God’s justice is perfectly displayed, unless the Christ is revealed in glory so that every knee bows and every tongue confesses that Jesus Christ is Lord to the glory of God the Father [Phil. 2:11], unless Christ claims His redeemed people, unless God’s triumph in Christ over death, sin, evil, and injustice is made universal. Put simply, unless every eye is dry and every tear is wiped away.
There is no Christian Gospel if history simply unwinds into a meaningless puddle, if the cosmos simply escapes into a cataclysmic black hole, or if the universe finally dies of exhausted energy. Without belief in a biblical eschatology, there is no Christian hope. Without a sense of perfect moral judgment in the end, the human heart is homeless.
