Human beings are made in the image of God (Genesis 1:26-27). In Genesis 2:7 we read that God formed Adam’s body from the dust of the ground, and then “breathed into his nostrils the breath of life, and the man became a living creature.” It is arguably true that God created humans with faculties and powers that reflect some of His own characteristics. However, since "God is spirit" (John 4:24), to be made in God's image cannot primarily refer to our physical being. It must importantly concern the human soul, or spirit.
Of course, this appreciation for the soul should not be construed as devaluing the body. The doctrines of both the incarnation and our future resurrection clearly reveal the value that God places on our bodies. At the same time, we must also recognize the special value of our souls. The unique capacities of human beings for rational thought, moral discernment, creativity and emotional experience, are intimately bound up with our embodiment while we are physically alive.
Yet it is crucially important to recognize that such capacities are retained by the soul (in a disembodied state) between death and resurrection (1 Samuel 28:3-19; Luke 16:19-31; Revelations 6:9-11). It is for reasons such as these that we should properly value the human soul (Matthew 16:26).
God has richly endowed the human soul so that we might exercise the creative gifts and abilities that He has given us to make the world a better place (Genesis 1:26-28). Believers have been yet further gifted that they might also be of service to the church, the body of Christ (1 Corinthians 12). Whatever we do, we are called to “work heartily” for the Lord, who will also reward us for our efforts (Colossians 3:23-24).
Since the soul gives life to our body and is the locus of personal identity, it plays an essential role in our calling and work. However, since Adam’s fall our souls are often restless, troubled, anxious and disquiet — and this always affects, and is sometimes exacerbated by, our work. We have been called and gifted to work, but we desperately need rest as well.
