The only complete way to overcome the [body image] problem is to have our beliefs about body image transformed by the Holy Spirit. As Heather Davis Nelson says in the Journal of Biblical Counseling:
In pursuing worldly beauty, we strive to become this elusive image in place of who we really are. You and I are created in the image of the living God. Our purpose is to reflect His image to the world. But since the fall, we let the world inscribe its image on us. It is the very picture of sin and ultimately death. Instead of being transformed to God’s image, we conform to the world’s image. We are hopelessly stuck in a lifeless cycle, exchanging God for the creature as our object of worship. But God in His mercy rescued us! In love, God sent Jesus Christ to take on the consequences of our idolatrous affair. He became sin so that we might become righteous. In Christ, God gives us freedom from sin’s power now and hope for its eradication in heaven. God makes you beautiful with the beauty of His Son, Jesus. It is in gazing at God’s image in Jesus Christ that you are transformed. Romans 12:1-2 says, “Therefore, I urge you, (sisters) in view of God’s mercy, to offer your bodies as living sacrifices, holy and pleasing to God—this is your spiritual act of worship. Do not be conformed any longer to the pattern of this world, but be transformed by the renewing of your mind.”
