The Garden of Eden remained upon the earth long after man had become an outcast from its pleasant paths. The fallen race were long permitted to gaze upon the home of innocence, their entrance barred only by the watching angels. At the cherubim-guarded gate of Paradise the divine glory was revealed. Hither came Adam and his sons to worship God. Here they renewed their vows of obedience to that law the transgression of which had banished them from Eden. When the tide of iniquity overspread the world, and the wickedness of men determined their destruction by a flood of waters, the hand that had planted Eden withdrew it from the earth. But in the final restitution, when there shall be “a new heaven and a new earth” (Revelation 21:1), it is to be restored more gloriously adorned than at the beginning.
Then they that have kept God's commandments shall breathe in immortal vigor beneath the tree of life; and through unending ages the inhabitants of sinless worlds shall behold, in that garden of delight, a sample of the perfect work of God's creation, untouched by the curse of sin—a sample of what the whole earth would have become, had man but fulfilled the Creator's glorious plan.30Patriarchs and Prophets, 62.
Adam is reinstated in his first dominion. Transported with joy, he beholds the trees that were once his delight—the very trees whose fruit he himself had gathered in the days of his innocence and joy. He sees the vines that his own hands have trained, the very flowers that he once loved to care for. His mind grasps the reality of the scene; he comprehends that this is indeed Eden restored.31The Great Controversy, 648.
Restored to the tree of life in the long-lost Eden, the redeemed will “grow up” (Malachi 4:2) to the full stature of the race in its primeval glory. The last lingering traces of the curse of sin will be removed, and Christ's faithful ones will appear in “the beauty of the Lord our God,” in mind and soul and body reflecting the perfect image of their Lord. Oh, wonderful redemption! long talked of, long hoped for, contemplated with eager anticipation, but never fully understood.32The Great Controversy, 645. Mar 354
Then the redeemed will be welcomed to the home that Jesus is preparing for them. There their companions will not be the vile of earth, liars, idolaters, the impure, and unbelieving; but they will associate with those who have overcome Satan and through divine grace have formed perfect characters. Every sinful tendency, every imperfection, that afflicts them here has been removed by the blood of Christ, and the excellence and brightness of His glory, far exceeding the brightness of the sun, is imparted to them. And the moral beauty, the perfection of His character, shines through them, in worth far exceeding this outward splendor. They are without fault before the great white throne, sharing the dignity and the privileges of the angels. SC 126
To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God. Revelation 2:7. KJV
