Easily done.
Revelation 6:9-10 (NKJV)
9 When He opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the testimony which they held.
10 And they cried with a loud voice, saying, "How long, O Lord, holy and true, until You judge and avenge our blood on those who dwell on the earth?"
If humans have no immortal soul that survives death, how do the souls of these Christian martyrs come to be in heaven crying out to God before the resurrection of the dead at Christ's return?
Luke 20:37-38 (NKJV)
37 But even Moses showed in the burning bush passage that the dead are raised, when he called the Lord 'the God of Abraham, the God of Isaac, and the God of Jacob.'38 For He is not the God of the dead but of the living, for all live to Him."
But Abraham, and Isaac, and Jacob are all dead. This means either that God is not the God of these men (which Scripture contradicts flatly) who are dead, or that these men are in some sense still alive. But for these men to be alive without their physical bodies, which is what this passage plainly implies, they would have to have an immaterial nature that survives the death of their physical body (an immortal soul).
1 Thessalonians 4:14-17 (NKJV)
14 For if we believe that Jesus died and rose again, even so God will bring with Him those who sleep in Jesus.
15 For this we say to you by the word of the Lord, that we who are alive and remain until the coming of the Lord will by no means precede those who are asleep.
16 For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first.
17 Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord.
If there is no immortal soul that exists beyond the death of the physical body, how can the Lord bring with him those who sleep? He doesn't resurrect the dead until verse 16 but he is bringing people with him in verse 14. What's going on here? The obvious explanation is that Jesus is bringing the departed souls of the righteous dead with him to be reunited with their bodies in the resurrection. No other explanation makes sense.
2 Corinthians 5:6-8 (NKJV)
6 So we are always confident, knowing that while we are at home in the body we are absent from the Lord.
7 For we walk by faith, not by sight.
8 We are confident, yes, well pleased rather to be absent from the body and to be present with the Lord.
Paul is here clearly indicating that it is possible to be absent from one's physical body and still exist (in the presence of the Lord). But how could this be possible without an immaterial nature that survives physical death? How can one be absent from one's body and yet present with the Lord if the soul does not survive the death of the body?
What does the Bible teach about the human soul?
1. It is distinct from the physical body, yet intimately connected to it and dwelling within the body. (Ps. 31:9; 131:2; Isa. 10:18; 26;9; Matt. 10:28)
2. It experiences and expresses sorrow, bitterness, joy, love, anguish, vexation, discouragement, etc. (Gen. 34:3; 42:21; Nu. 21:4; Deut. 6:4, 5; Ju. 16:16; Job 3:20; Ps. 35:9)
3. It is capable of choosing and remembering. (Job. 7:15; La. 3:20)
4. It may, as a unique, personal entity depart, and return to, the physical body that housed it. (Gen. 35:18; 1Ki. 17:21, 22)
5. As a term, used interchangeably in Scripture with the term "spirit." (Isa. 26:9)
Genesis 2:7 (NKJV)
7 And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living being.
Ron Rhodes observes,
"It is true that in the Old Testament, the Hebrew word for soul (nephesh) can be used in reference to a living being. Genesis 2:7 is clearly an example of this. But because the word can be used in this sense does not mean that it is limited to this sense, or that man does not have an immaterial nature...Indeed, Genesis 2:7 is telling us what man is (a living being), not what he is not. In other words, while Genesis 2:7 affirms that man is a living being, it does not deny in any way that man has an immaterial nature." ("Reasoning from the Scriptures" by Ron Rhodes. pg. 308)
Genesis 35:18 (NKJV)
18 And so it was, as her (Rachel's) soul was departing (for she died), that she called his name Ben-Oni; but his father called him Benjamin.
1 Kings 17:21-22 (NKJV)
21 And he stretched himself out on the child three times, and cried out to the Lord and said, "O Lord my God, I pray, let this child's soul come back to him."
22 Then the Lord heard the voice of Elijah; and the soul of the child came back to him, and he revived.
In both these passages the soul is not identified as merely an animating energy that came from God and is returned to Him. When Rachel dies in childbirth it is her soul that departs her body, not God's life-force. When Elijah calls upon God to revive the dead boy he asks, not for God to give the boy some of His divine life-energy, but specifically for the boy's soul to be returned to his body. It is "the soul of the child" that comes back to the child's dead body and causes its revival, not merely the animating breath of God.
Both passages also clearly differentiate between the soul and the body. In both passages the soul continues to exist beyond the decease of the body.
Matthew 17:1-3
1 Six days later Jesus took with Him Peter and James and John his brother, and led them up on a high mountain by themselves.
2 And He was transfigured before them; and His face shone like the sun, and His garments became as white as light.
3 And behold, Moses and Elijah appeared to them, talking with Him.
How is the appearance of Moses and Elijah, who were dead for centuries before their appearance with Christ, possible? If there was only an animating energy that returned to God when they died rather than their unique, immaterial souls, how are they speaking with Jesus on the mountain? Apparently, it is possible after physical death to exist as a distinct spiritual entity capable of speech and possessing a discernible form.
Luke 23:46-47
46 And when Jesus had cried out with a loud voice, He said, "Father, 'into Your hands I commit My spirit.' "Having said this, He breathed His last.
47 So when the centurion saw what had happened, he glorified God, saying, "Certainly this was a righteous Man!"
The word "spirit" here is translated from the Greek word "pneuma," which has a variety of meanings in Scripture: wind, breath, life-spirit, soul, the spirit as part of the human personality, the spirit of God, the spirit of Christ, and the Holy Spirit. Context rules out most of these meanings. It doesn't make sense for Jesus to commend his "wind" or "breath" to the Father. It doesn't make any better sense for Jesus to be committing "the spirit of God" or the "Holy Spirit" to the Father. From a plain reading of the passage it is clear Jesus is committing his immaterial human soul or spirit to the Father.
Philippians 1:21-23
21 For to me, to live is Christ, and to die is gain.
22 But if I live on in the flesh, this will mean fruit from my labor; yet what I shall choose I cannot tell.
23 For I am hard pressed between the two, having a desire to depart and be with Christ, which is far better.
How could being dead and thus non-existent be "gain" to Paul? Clearly, he did not think the "gain" of which he was speaking was the extinction of his soul with the death of his body, but the departure of his soul from his body to be with Christ. And Paul is not speaking here of a future resurrection. The aorist infinitive ("to live") is linked by a single article with a present infinitive ("to be with Christ"). Thus the infinitives belong together.
"The single article ties the two infinitives together, so that the actions depicted by the two infinitives are to be considered two aspects of the same thing, or two sides of the same coin." - (Reasoning from the Scriptures with Jehovah's Witnesses, Ron Rhodes, pg. 317.)
And so on.
