For a Christian, there are two components that allow us to function in the spiritual realm as shown in the figure: a person’s spirit and their soul (Hebrews 4:12). A person’s spirit is what allows them to have a relationship with Jesus Christ. This component of a person (whether they have a relationship with Christ or not) allows them to live after their physical body dies. For those who have a relationship with Jesus Christ, their spirit will live forever with Christ in the Kingdom of God (Revelation 22:12-14). For those who do not, they will exist in hell separated from God forever (Revelation 20:15). The soul, on the other hand, is what allows a person to function daily. We refer to this component as a person’s cognitive and social abilities. The soul perishes along with the physical body when a person dies. It is impossible for us as humans to psychologically distinguish between the spirit and the soul. To us, it seems as one entity. But to God, they are separate (Hebrews 4:12).
