Does it really matter how old the earth is, especially in light of the church’s need to share the gospel? These two topics are more closely related than most Christians realize.

Can a person believe in an old earth and an old universe (millions or billions of years in age) and be a Christian?

First of all, let’s consider three verses that sum up the gospel and salvation. 1 Corinthians 15:17 says, “If Christ is not risen, your faith is futile; you are still in your sins!” Jesus said in John 3:3, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.” Romans 10:9 clearly explains, “If you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved.”

Numerous other passages could be cited but not one of them states in any way that a person has to believe in a young earth or universe to be saved.

And the list of those who cannot enter God’s kingdom, as recorded in passages like Revelation 21:8, certainly does not include “old earthers.”

Many great men of God who are now with the Lord have believed in an old earth. Some of these explained away the Bible’s clear teaching about a young earth by adopting the classic gap theory. Others accepted a day-age theory or positions such as theistic evolution, the framework hypothesis, and progressive creation.

Scripture plainly teaches that salvation is conditioned upon faith in Christ, with no requirement for what one believes about the age of the earth or universe.

Now when I say this, people sometimes assume then that it does not matter what a Christian believes concerning the supposed millions of years age for the earth and universe.

Even though it is not a salvation issue, the belief that earth history spans millions of years has very severe consequences. Let me summarize some of these.

Authority Issue

The belief in millions of years does not come from Scripture, but from the fallible methods that secularists use to date the universe.

To attempt to “fit” millions of years into the Bible, you have to invent a gap of time that almost all Bible scholars agree the text does not allow—at least from a hermeneutical perspective. Or you have to reinterpret the “days” of creation as long periods of time (even though they are obviously ordinary days in the context of Genesis 1). In other words, you have to add a concept (millions of years) from outside Scripture, into God’s Word. This approach puts man’s fallible ideas in authority over God’s Word.

As soon as you surrender the Bible’s authority in one area, you “unlock a door” to do the same thing in other areas. Once the door of compromise is open, even if ajar just a little, subsequent generations push the door open wider. Ultimately, this compromise has been a major contributing factor in the loss of biblical authority in our Western world.

The church should heed the warning of Proverbs 30:6, “Do not add to His words, lest He rebuke you, and you be found a liar.”

Contradiction Issue

A Christian’s belief in millions of years totally contradicts the clear teaching of Scripture. Here are just three examples:

Thorns. Fossil thorns are found in rock layers that secularists believe to be hundreds of millions of years old, so supposedly they existed millions of years before man. However, the Bible makes it clear that thorns came into existence after the curse: “Then to Adam He said, ‘Because . . . you have eaten from the tree of which I commanded you, saying, “You shall not eat of it”: Cursed is the ground for your sake. . . . Both thorns and thistles it shall bring forth for you’” (Genesis 3:17–18).

Disease. The fossil remains of animals, said by evolutionists to be millions of years old, show evidence of diseases (like cancer, brain tumors, and arthritis). Thus such diseases supposedly existed millions of years before sin. Yet Scripture teaches that after God finished creating everything and placed man at the pinnacle of creation, He described the creation as “very good” (Genesis 1:31). Certainly calling cancer and brain tumors “very good” does not fit with Scripture and the character of God.

Diet. The Bible clearly teaches in Genesis 1:29–30 that Adam and Eve and the animals were all vegetarian before sin entered the world. However, we find fossils with lots of evidence showing that animals were eating each other—supposedly millions of years before man and thus before sin.

Death Issue

Romans 8:22 makes it clear that the whole creation is groaning as a result of the Fall—the entrance of sin. One reason for this groaning is death—the death of living creatures, both animals and man. Death is described as an “enemy” (1 Corinthians 15:26), which will trouble creation until one day it is thrown into the lake of fire.

Romans 5:12 and other passages make it obvious that physical death of man (and really, death in general) entered the once-perfect creation because of man’s sin. However, if a person believes that the fossil record arose over millions of years, then death, disease, suffering, carnivorous activity, and thorns existed millions of years before sin.

The first death was in the Garden of Eden when God killed an animal as the first blood sacrifice (Genesis 3:21)—a picture of what was to come in Jesus Christ, the Lamb of God, who would take away the sin of the world. Jesus Christ stepped into history to pay the penalty of sin—to conquer our enemy, death.

By dying on a cross and being raised from the dead, Jesus conquered death and paid the penalty for sin. Although millions of years of death before sin is not a salvation issue per se, I personally believe that it is really an attack on Jesus’ work on the cross.

Recognizing that Christ’s work on the cross defeated our enemy, death, is crucial to understanding the “good news” of the gospel: “And God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away” (Revelation 21:4).

Rooted in Genesis

All biblical doctrines, including the gospel itself, are ultimately rooted in the first book of the Bible.

  • God specially created everything in heaven and earth (Genesis 1:1).
  • God uniquely created man and woman in His image (Genesis 1:26–27).
  • Marriage consists of one man and one woman for life (Genesis 2:24).
  • The first man and woman brought sin into the world (Genesis 3:1–24).
  • From the beginning God promised a Messiah to save us (Genesis 3:15).
  • Death and suffering arose because of original sin (Genesis 3:16–19).
  • God sets society’s standards of right and wrong (Genesis 6:5–6).
  • The ultimate purpose of life is to walk with God (Genesis 6:9–10).
  • All people belong to one race—the human race (Genesis 11:1–9).
