A big question that affects both life and life after death is, “What are we?” You would think that we would know this answer before anything else, but this question is very deep.
Those with a materialistic world view would say that we are just a body. To be crasser about it, one famous evolutionist says that we are just “machines made out of meat.” We are just chemistry doing what chemistry does. This philosophy either makes you feel liberated to do whatever feels good or plunges you into the depth of despair because you are nothing. You have no purpose. You have no future.
The machine made from meat idea obviously doesn’t agree with Scripture. I would have to say that it does meet with experience either.
Another view is to see yourself as just your consciousness. That you are a spiritual being temporarily occupying a physical form. This worldview has the support of the fact that we will all die and our bodies will decay (unless we are alive at Jesus’ return). It doesn’t have the support of both Jesus’ resurrection and the promise of our own resurrection. The earthly body may need a total remake, but it is an important part of you.
I would like to consider the following passage:
23 Now may the God of peace himself sanctify you completely, and may your whole spirit and soul and body be kept blameless at the coming of our Lord Jesus Christ.
1 Thessalonians 5:23 (ESV)
Words mean what they writer thinks that mean. So someone may use soul and spirit as synonyms, while another is thinking of two distinct things. Since Scripture is inspired by the Holy Spirit, I would expect that these words have distinct meanings, especially considering this one:
12 For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart.
Hebrews 4:12 (ESV)
The Greek behind “soul and spirit” is “psyche” and “pneuma”. I don’t think we should get too Freudian because of psyche. I like this definition, “The psyche is the is life that the spirit gives to the body as long as the two are connected.” (R.C.H. Lenski) So our soul is our consciousness which includes such things as thoughts, emotions, feelings, desires, memories. The spirit is the immaterial/extra-dimensional part of what we are. This definition is backed by how the word “soul” is used throughout Scripture. For example:
I praise you, for I am fearfully and wonderfully made.
Psalm 139:14 (ESV)
Wonderful are your works; my soul knows it very well.
Our spirit then becomes something that we experience indirectly. At death our spirit and our bodies are divided because of sin. What do we “experience” then? Near Death Experiences may give some insight. If we are temporarily dead, then perhaps we are temporarily in a state of separation of spirit and body. We have senses but they don’t use our sensory organs. For example, people can “see” things in the operating room with their eyes closed and their brain flat-lined. We may feel that our spirit is all that we need and that a body and the embodiment of our spirit (our soul) is not necessary. But we have been created to be embodied. Hence the resurrection.
While the information about such details is sparse, I believe that even our experience of Heaven prior to our resurrection is embodied. It is just a body that is a part of Heaven’s time and space. More about that here:https://afterdeathsite.com/2020/02/04/we-will-be-made-multi-dimensional/
Eventually, we will have and will be both a being who can exist in this universe and one that can exist in Heaven: One spirit, a resurrected Earthly body and a soul from the interaction of the two, also a Heavenly body and a soul for that embodiment.
