I like Bavinck’s broad notion of the image of God because it allows us to apply it to different situations like working as chaplaincy.
I believe human beings do not have the image of God. The image of God then is not something or a characteristic that we all bear, have, or acquire. As human beings, we all are the image of God. We all are—body, soul, and spirit—are the image of God integrally. So I do not think there is a difference between the image and likeness of God, since all aspects of the human being reflects perfectly God. All that is God is found in us in a limited way—i.e. essence, character, virtues, abilities, etc. This allows us to affirm that our bodies, for example, are not outside of such an image, but it is an essential part of it.
Our bodies let us to interact with the physical world—a body that God created healthy and capable in all aspects. Thus, dominion over earth would be on the main characteristics of the image of God. Neither angels, demons, animals, or plants have dominion over creation, except God and human beings. And that dominion should be understood not as exercising unlimited power on creation, but about representing God in the care of the creation. One thing I like to highlight is that our identity is formed before one may do something. Human beings are not what they do, but they act because of who they are. For instance, do we sin because we are sinners or are we sinners because we sin? I strongly believe that although both are valid points, the first option has more validity or soundness than the second option. Therefore, despite all the features of the image of God human beings have, we cannot work apart from God because God created us intentionally to be always in communication with him.
Finally, I think that we reflect more the image of God on our spiritual aspect than our physicality. For example, human strength cannot be easily compared to God’s strength, but our ability to show love and compassion to others reflect a lot God’s character. Besides, when sin corrupted human nature, we lost the ability to reflect God in the ways He wanted us to do it, so that Christ restored such image in us in order we may have communication with God again and reflect him in the best way possible.
