What does it mean that God created man in His own image?
The Bible nowhere attempts to explain in specific detail what God meant when He said He would create man in His own image. It simply tells us that He did. (Genesis 1:26-27) That being said, I believe it is possible to uncover the answer to this question from studying the Word of God.
One thing we are certain about is that being made in God’s image does not mean that we bear a physical resemblance to Him. The Bible tells us in no uncertain terms that the Creator of the Universe is a Spirit, and invisible. (John 4:24; 1 Timothy 1:17)
It should also be stated that mankind is unique among God’s creation in the sense of being made in His image. This is said of no other created thing or being.
Basically being made in God’s image means that we share in His nature—at least partially. We call those aspects of Himself that are shared with mankind His communicable attributes. These include, personality, the ability to reason, wisdom, knowledge, love, justice, as well as the capacity for knowing God and having fellowship with Him.
