The second Adam, Jesus, is also called First Fruit. Fruit grows on a tree.
So the damage the first Adam did by stealing the fruit is undone by the second Adam.
Ah, yes...Look at it this way--Jesus is the first fruits of them that died.
1 Corinthians 15:20
But now is Christ risen from the dead, and become the firstfruits of them that slept."slept"G2837
κοιμάω
koimaō
koy-mah'-o
From G2749;
to put to sleep, that is, (passively or reflexively) to slumber; figuratively
to decease: - (be a-, fall a-, fall on) sleep, be dead.
Jesus is the tree of life.
What seed brought forth the firstfruit?
15And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.--Gen 3
Adam and Eve left the garden carrying the seed.
Job 19:25
For I know that my redeemer liveth, and that he shall stand at the latter day upon the earth:
for now is Christ risen from the dead
the first fruits of them that slept
for I know that my redeemer liveth
and that he shall stand at the latter day upon the earth
and though worms destroy this body
yet in my flesh shall I see God.
