II Corinthians 3:17-18

Later on in the Bible, we see terms like brother, sister, father, mother, wife, sons, daughters, adoption, and family, but what is the image of God? Because we are physical, our first reaction is to always think or to look for something physical, meaning a form or a shape that will give us some idea, some concept, of what it is we are being made into, but there is none because that is not God's specific purpose.

There is God's purpose in much clearer language. We are being transformed from the image of man to the image of Jesus Christ. What sort of an image do we have of Him? We do not know what He looked like; we have no form or shape. Instead what God gave us was the image of a life lived. So we are being transformed into the image of that life that was lived and the means for accomplishing this is the Spirit of the Lord, the Holy Spirit, or we might say as Peter said, "by the imparting of the divine nature."

II Corinthians 3:17-18

So through Christ's life, we see how amazing God is and understand what He is truly like. As we learn more, God's Spirit helps us grow. Becoming morally Christ-like is a gradual process, and it is called in Scripture sanctification. The more we follow Him closely, the more we will become like Him.
