How do we know that man is created in the image of God?

The doctrine of man being created in the image of God is explicitly outlined in Genesis 1:26-27, where it is proclaimed, 'Let us make man in our image, after our likeness.' This foundational truth establishes humanity's unique distinction among God's creations. Unlike the other created beings, man is endowed with attributes such as reason, moral understanding, and the capacity for relationship with God. Although sin has marred this image, it remains inherently valuable. This understanding fuels the biblical perspective that all human life is sacred and worthy of dignity and respect. As Paul affirms in Ephesians 2:10, believers are 'created in Christ Jesus for good works,' further indicating that being made in God's image aligns us with His purposes and design.
