Gen 1:26 Then God said; "Let us make man in our image, in our likeness..."
From the moment of our creation, we are made in the image of God. From the moment of our salvation, we are conformed to the likeness of his Son. God has given us a sound mind and our identity is in Christ. Our illness does not define us and our character is not in question. The struggle we face will fade away and we will have eternal glory.
Rom 8:29 For those God forknew He also predestined to be conformed to the likeness of His Son.
