Eternal

The English word “eternal” in the Bible most often translates two key biblical words. The Hebrew word ʿôlām (עוֹלָם) and the Greek word aiōnios (αἰώνιος)

These words carry the idea of unending time, perpetual duration, or that which belongs to the age to come. Yet each has nuances worth exploring.

The Hebrew Word: עוֹלָם (ʿôlām)

Root idea: “hidden”, “concealed”, “beyond the horizon”

Sense: a long duration, antiquity, perpetuity, or endlessness.

ʿÔlām does not always strictly mean “eternal” in a philosophical sense. Instead, it points to something so long-lasting that its end is beyond sight, thus practically everlasting, depending on context.

Key Examples

1. God’s Eternal Nature

“The eternal God is a dwelling place…” (Deuteronomy 33:27)

Here ʿôlām refers to God’s unending existence, His permanence and timelessness.

 

 

2. Eternal Covenant

“I will establish My covenant… for an everlasting covenant.” (Genesis 17:7)

God’s covenants stemming from His character share this sense of unending duration.

3. Everlasting Kingdom

“Your kingdom is an everlasting kingdom.” (Psalm 145:13)

This expresses God’s rule as truly perpetual.

Though the word can sometimes refer to long but finite periods (e.g., the “perpetual” priesthood of Aaron), when applied to God, His attributes, or eschatological realities, ʿôlām takes on the sense of true eternity.

The Greek Word: αἰώνιος (aiōnios)

Deriving from aiōn (“age”), aiōnios means “eternal”, “everlasting”, “pertaining to the age to come” and “without beginning or end”, depending on context.

In the New Testament, especially in the writings of John and Paul, aiōnios commonly describes the unending life of God and the unending consequences of His judgment.

 

 

Key Examples

1. Eternal Life

“For God so loved the world… that whoever believes in Him shall not perish, but have eternal life.” (John 3:16)

Aiōnios zōē refers not just to duration but quality, life that flows from God Himself.

2. Eternal Judgment

“These will go away into eternal punishment, but the righteous into eternal life.” (Matthew 25:46)

Here the same adjective (aiōnios) describes both outcomes, underscoring equal duration and permanence.

3. Eternal God

“To the eternal God, immortal, invisible…” (1 Timothy 1:17)

This reflects God’s timeless existence, He is beyond the constraints of created time.

While aiōnios sometimes carries the idea of “belonging to the coming age,” in most theological contexts it unequivocally means unending.

Theological Summary

1. Eternal Means More Than “Long-Lasting”

Both biblical words carry the idea of unmeasured duration. Yet when applied to God and His purposes, they also emphasize timelessness, unchangeability and God’s sovereign permanence.

2. Eternal Life Is Both Present and Future

According to John’s Gospel, believers possess eternal life now (John 5:24), and yet its full experience comes in the age to come.

3. Eternal Judgment Is Truly Everlasting

Because Jesus uses aiōnios for both punishment and life in Matthew 25:46, the New Testament presents both as equally final and enduring.

Summary Definition

Hebrew: ʿôlām - that which endures indefinitely; hidden beyond the horizon; everlasting when referring to God and His works.

Greek: aiōnios - everlasting; without end; belonging to the age to come; enduring as long as God’s own life.

In Scripture, “eternal” conveys unchanging, unending, divinely-given existence or consequence, rooted in God’s own eternal nature.
