There is so much that is important and encouraging here, but Paul may save the best for last. We have a goal and a hope that we are waiting for, so everything we do while we wait has purpose (15:58)!
Paul continues this section by rebuking Christians who have been listening to the lies of unbelievers about the resurrection. He then goes on to compare the difference between our earthly bodies and our resurrection bodies:
— Our old bodies:
1. Are perishable.
2. Are sown in dishonor.
3. Are sown in weakness.
4. Are sown as natural bodies.
5. Are sown bearing the likeness of the first Adam.
— Our new bodies:
1. Will be raised imperishable.
2. Will be raised in glory.
3. Will be raised in power.
4. Will be raised a spiritual body.
5. Will be raised bearing the likeness of Christ.
The reason? Flesh and blood cannot inherit God’s Kingdom (15:50). When Jesus does come back, all believers who are alive will go to heaven without dying (15:51). This will occur in the amount of time it takes to blink an eye (15:52). The last trumpet will signify the fulfillment of this promise (15:52). However, since flesh and blood cannot inherit the kingdom, departed believers will exchange their corrupted bodies for incorruptible ones (15:52c), and living believers will exchange their mortal bodies for immortal ones (15:53). The Old Testament prophets Isaiah and Hosea predicted this (Isa. 25:8; Hos. 13:14). To God be the glory!
