As is the one made of dust, such are those who are also made of dust; and as is the heavenly, such are they also that are heavenly.
Adam was earthly, frail, corruptible, mortal; all who descend from him share that nature. But Christ is heavenly in His glorified body, and those who belong to Him will be fashioned like unto His glorious body.

The objection cuts two ways: how can the dead be raised at all, and what sort of body will they wear? The first doubters deny God has the power; the second merely wonder at the form. But look at the corn you sow each year, it must rot before it springs up alive. If God quickens grain, why call it impossible that He raises men?

Commenting on 1 Corinthians 15:35-50
As is the earthy--namely, Adam. they . . . that are earthy--All Adam's posterity in their natural state (Joh 3:6-7). the heavenly--Christ. they . . . that are heavenly--His people in their regenerate state (Phi 3:20-21). As the former precedes the latter state, so the natural bodies precede the spiritual bodies.
