I wonder which part of us the soul is.
I believe we have many parts. Everyone has ego(or free will), child, critics and there are also other parts of us and we have our experiences during our life, we have our mind and feelings.
We have also the spirit that is given from above and can be more or less(I believe its pure energy) but the soul is something else. I wonder what is the soul? Does anyone has some insight on this?
(I believe its pure energy)
This is correct ... it is the breath of life (energy given from God).
A "soul" is not something we possess, rather it is what we are ... not something separate from us .... the soul is a person.
Scripture gives us a simple equation for understanding the nature of humans:
Body (dust of the ground; the earth's elements) plus
Breath of life ("spirit" of life from God) equals
A living person (a soul).
Nowhere does the Bible speak of the soul as an immortal entity capable of living apart from our body. Neither does it speak of the spirit as an entity which can exist independent of our physical nature. We are not made of independent parts temporarily connected, but of body, soul and spirit (breath of life) in one indivisible whole.
In the Old Testament, the Hebrew word ruach occurs 377 times and is translated "wind ... .. breath," or "spirit" (Gen. 8: 1), "life principle" (Gen. 6:17; 7:22), "courage" (Josh. 2:11), "vitality" or "strength" (Judg. 15:19), "disposition" (Isa. 54:6), and "moral character" (Ezek. 11:19).
The "spirit" or "breath" of a person is identical with the "spirit" or "breath" of animals (Eccles. 3:19). This "spirit" or "breath" of a person returns to God at the time of death, and the body returns to the dust where it came from (Job 34:14; Eccles. 12:7). It is also translated "Spirit of God" (Isa. 63:10). In the New Testament the Greek word pneuma is similarly translated as "spirit" or "to breathe." It is also translated as ,"mood," "attitude," or "state of feeling" (Rom. 8:15; 1 Cor. 4:21; 2 Tim. 1:7; 1 John 4:6). Like ruach, it is sometimes translated "Spirit of God" (1 Cor. 2:11, 14; Eph. 4:30; Heb. 2:4; 1 Pet. 1:12; 2 Pet. 1:21).
Neither in the Old Testament nor the New Testament does ruach or pneuma refer to an intelligent entity capable of existence apart from the body
There is nothing immortal about us ... we receive immortality when Jesus returns.
