Question: "Is the human soul mortal or immortal?"
Answer: Without a doubt the human soul is immortal. This is clearly seen in many Scriptures in both the Old and New Testaments: Psalm 22:26; 23:6; 49:7-9; Ecclesiastes 12:7; Daniel 12:2-3; Matthew 25:46; and 1 Corinthians 15:12-19. Daniel 12:2 says, “Multitudes who sleep in the dust of the earth will awake: some to everlasting life, others to shame and everlasting contempt.” Similarly, Jesus Himself said that the wicked “will go away to eternal punishment, but the righteous to eternal life” (Matthew 25:46). With the same Greek word used to refer to both “punishment” and “life,” it is clear that both the wicked and the righteous have an eternal/immortal soul.
The unmistakable teaching of the Bible is that all people, whether they are saved or lost, will exist eternally, in either heaven or hell. True life or spiritual life does not cease when our fleshly bodies pass away in death. Our souls will live forever, either in the presence of God in heaven if we are saved, or in punishment in hell if we reject God’s gift of salvation. In fact, the promise of the Bible is that not only will our souls live forever, but also that our bodies will be resurrected. This hope of a bodily resurrection is at the very heart of the Christian faith (1 Corinthians 15:12-19).
While all souls are immortal, it is important to remember that we are not eternal in the same way that God is. God is the only truly eternal being in that He alone is without a beginning or end. God has always existed and will always continue to exist. All other sentient creatures, whether they are human or angelic, are finite in that they had a beginning. While our souls will live forever once we come into being, the Bible does not support the concept that our souls have always existed. Our souls are immortal, as that is how God created them, but they did have a beginning; there was a time they did not exist.
