“While we look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal, but the things which are not seen are eternal.” 2 Corinthians 4:18 (NASB)
“Temporal” means transitory, temporary, things that are limited by time and will pass away. The term is especially applicable to things of this life. They are for but a short time, they soon will pass.
The things of the earth are temporal, “but that things which are not seen are eternal.” How foolish for man to spend his time neglecting the inner man. “For what will it prophet a man if he gains the whole world and forfeits his soul? Or what will a man give in exchange for his soul?” Matthew 16:26 (NASB). The “things which are not seen” are spiritual, things provided of God through the death of His Son, things we will receive beyond the grave.
God is eternal. He is from everlasting to everlasting (Psalm 90:2). Jesus is eternal. He was in the beginning with God, He is with God, and He is now preparing a place for the redeemed where we can spend eternity with Him. “But just as it is written, ‘Things which eye has not seen and ear has not heard, and which have not entered the heart of man, all that God has prepared for those who love Him.'” 1 Corinthians 2:9 (NASB) All those things which are too glorious for man to look upon or describe, those “things not seen,” are eternal.
Heaven’s joys are unending. In that celestial city where the redeemed will dwell, there will be no separation. There will be no crepe on the doorknob, no deathbed experience, no cemeteries, no sad goodbye’s to loved ones. There will be no night there, no end to that glorious day with all its joys. All who enter there have the assurance that such joy and glory shall endure throughout the eternal ages.
