I have been struck lately concerning the biblical nature of time and eternity. In Christoplatonism, time and eternity are antithetical. They are enemies, because time is part of materiality (which is bad) and eternity is basically the same as immateriality. Immaterial “heaven” is static and timeless, while materiality is dynamic and timely. However, within the biblical worldview, the heavens and earth are both dynamic and timely. Thus, time and eternity go hand-in-hand. They lie on the same simple timeline, which starts at creation and goes on to consummation. “This age” is characterized by the Cross—the Messiah came the first time to bear sins—and he will come the second time to usher in “the age to come” by bringing salvation, i.e. resurrection of the dead, messianic kingdom, new earth, etc.
The biblical language even reflects this simple understanding of time and history. The Greek word for “age” is aion. The Greek word for “eternity” is simply the plural form of “age”, i.e. aiones. Thus, eternity is seen as “unending ages”, which relate on the same continuum as “this age”. Rather than the Christoplatonic understanding of timelessness, the biblical concept of eternity is unending time. Jesus will return, create a new heavens and new earth, punish the wicked with eternal fire, and reward the righteous with eternal life. Glory.
