Human beings are made in the image of God and are often referred to in terms of the physical (body) and the spiritual (soul and/or spirit). With regard to the spiritual realm, a pertinent question is whether soul and spirit refer to the same thing. Are humans made up of three parts: body, soul, and spirit? Or are human beings made up of two parts: body and soul and/or spirit? This is a difficult question, and I know people who hold different views. To discuss this issue, we must begin by surveying the biblical usage of these terms. Looking at Spirit in the Bible In the OT, the word for spirit (רוּחַ) can mean the following: In the NT, the Greek word for spirit (πνεῦμα) has virtually the same meanings: In comparing the OT and NT usage, the word for spirit is used similarly. It appears that when spirit denotes a human being it usually refers to the personality of the individual. We still retain that use today when we say, “He was mean-spirited.” Well, we mean that his personality was mean. Looking at Soul in the Bible In the OT, the word for soul (נֶפֶשׁ) has the following meanings: In the NT, the word for soul (ψυχή) has the following meanings: Thus, in biblical usage, there seems to be an overlap between the usage of soul and spirit when referring to human beings. In fact, a proper distinction between soul and spirit is not always possible. Be that as it may, I think there are three observations that we can make in looking at the evidence. Three Observations about the Usage of Soul and Spirit in the Bible First, in general, spirit refers to the immaterial aspects of life, whereas soul refers to the whole of living itself (including the desires and emotions of life). Second, when used together in certain passages (cf. 1 Thess 5:23; Heb 4:12), a strict distinction between soul and spirit is probably not what is being stressed. The entirety is likely what is being stressed. Have you heard the saying, “That is the heart and soul of the matter?” When we hear that saying, we do not assume that heart and soul are being used in juxtaposition to communicate a difference. Rather, we assume that heart and soul are used in unity to communicate entirety and completeness. Sometimes the Bible adds terms together for just such a purpose. Third, biblical authors did not view human beings as divisible into soul/spirit and body. Scripture portrays the soul and spirit as an integral part of the person, and likewise, the body is intimately connected to the soul/spirit as an essential part of what it means to be human. The separation of the physical and spiritual seems to come from Platonic philosophy and not the Bible. The Bible always assumes a united personhood of immaterial characteristics (soul and spirit) along with material (body). Even in looking forward to the eternal state in the resurrection, the Bible is very holistically focused. In conclusion, it seems that human beings consist of an immaterial and a physical aspect. The descriptions of soul and spirit seem to refer to the immaterial aspect of humanity. The similar range of meanings and the combined usage of soul and spirit point toward viewing these two concepts similarly within the biblical portrayal of personhood.
