if humanity is god's image, how does our treatment of other humans reflect on that image?

Adds the setting and its conversation across both testaments.

Genesis 1:26-27

“26 God said, “Let’s make man in our image, after our likeness. Let them have dominion over the fish of the sea, and over the birds of the sky, and over the livestock, and over all the earth, and over every creeping thing that creeps on the earth.” 27 God created man in his own image. In God’s image he created him; male and female he created them.”

This passage comes from the very beginning of the Bible, in the first creation account. It describes God's creation of humanity as the pinnacle of his work, made uniquely "in his image" and given a special role over the rest of creation.

What does it mean for us to actively honor or diminish God's image in one another through our actions and attitudes?

Then — the setting

The book of Genesis was likely compiled and written down over centuries, with its final form taking shape during or after the Babylonian exile (around the 6th-5th century BCE). The audience was the Israelite community, either newly formed or returning from exile, who needed to understand their origins, identity, and special relationship with God. In the ancient Near East, kings often set up statues of themselves to signify their rule over a territory. The concept of humanity being created in God's 'image' (Hebrew: *tselem*) and 'likeness' (Hebrew: *demut*) would have conveyed the idea that every human being, not just a king, represents God's presence and authority on Earth, tasked with stewarding creation.

Across the Testaments

The Old Testament introduces the fundamental idea that all humanity bears God's image, establishing a basis for human dignity and the value of every life (e.g., in the Noahic covenant, Genesis 9:6, which prohibits murder because humans are made in God's image). The New Testament affirms and deepens this concept. Paul refers to Christ as 'the image of the invisible God' (Colossians 1:15) and says believers are being 'conformed to the image of his Son' (Romans 8:29), suggesting that while humanity's image of God was marred by sin, it is being restored and perfected in Christ. This underscores that our treatment of others, especially the vulnerable, reflects our understanding of their intrinsic worth as God's image-bearers, and ultimately, our relationship with God.
