The Greek word aionios

Related to the Greek noun “aion,” the Greek adjective “aionios” meant “eternal” or “everlasting.”  This term is used in the books of Matthew, Mark, Luke, John, Acts, Romans, Second Corinthians, Galatians, Second Thessalonians, First Timothy, Second Timothy, Titus, Philemon, Hebrews, First Peter, Second Peter, First John, Jude, and Revelation.  Of the approximately 70 times this word is used in the New Testament, all but about five of these places refer to God or something associated with him such as salvation.

The unsaved will be cast into an “eternal” fire (Mt. 18:8) while the saved will receive “eternal” life (Mt. 19:29).  Eternal life is found through Christ (Jn. 3:15-16; Rom. 6:23), but many will suffer “eternal” destruction (2 Thess. 1:9).

The Holy Spirit is deity, so He can be described as the “eternal” Spirit (Heb. 9:14).
