The promise is clear: God invites us to make exchanges. The documentation is persuasive. Exchanges took place repeatedly with Israel and with Jesus. The expectation is reinforced in the final book of Scripture, Revelation, which entered the Christian church during a time of great suffering, with Isaian phrases that have kept the comfort current: “They shall hunger no more, neither thirst any more; the sun shall not strike them, nor any scorching heat….And God will wipe away every tear from their eyes….Neither shall there be mourning nor crying nor pain any more” (Revelation 7:16–17; 21:4).
