(from Great Controversy, pg 675-8)
Human language is inadequate to describe the reward of the righteous. It will be known only to those who behold it. No finite mind can comprehend the glory of the Paradise of God.
In the Bible the inheritance of the saved is called "a country." Hebrews 11:14-16. There the heavenly Shepherd leads His flock to fountains of living waters. The tree of life yields its fruit every month, and the leaves of the tree are for the service of the nations. There are ever-flowing streams, clear as crystal, and beside them waving trees cast their shadows upon the paths prepared for the ransomed of the Lord. There the wide-spreading plains swell into hills of beauty, and the mountains of God rear their lofty summits. On those peaceful plains, beside those living streams, God's people, so long pilgrims and wanderers, shall find a home.
We shall ever feel the freshness of the morning and shall ever be far from its close. The light of the sun will be superseded by a radiance which is not painfully dazzling, yet which immeasurably surpasses the brightness of our noontide. The glory of God and the Lamb floods the Holy City with unfading light. The redeemed walk in the sunless glory of perpetual day.
There, immortal minds will contemplate with never-failing delight the wonders of creative power, the mysteries of redeeming love. Every faculty will be developed, every capacity increased. The acquirement of knowledge will not weary the mind or exhaust the energies. There the grandest enterprises may be carried forward, the loftiest aspirations reached, the highest ambitions realized; and still there will arise new heights to surmount, new wonders to admire, new truths to comprehend, fresh objects to call forth the powers of mind and soul and body.
All the treasures of the universe will be open to the study of God's redeemed. Unfettered by mortality, they wing their tireless flight to worlds afar--worlds that thrilled with sorrow at the spectacle of human woe and rang with songs of gladness at the tidings of a ransomed soul. With unutterable delight the children of earth enter into the joy and the wisdom of unfallen beings. They share the treasures of knowledge and understanding gained through ages upon ages in contemplation of God's handiwork. With undimmed vision they gaze upon the glory of creation--suns and stars and systems, all in their appointed order circling the throne of Deity. Upon all things, from the least to the greatest, the Creator's name is written, and in all are the riches of His power displayed.
