Whilest your question is good, being made in the image of God is an entirely different topic from predestination. I do have a separate study on this, but what I will say, in short, is this... being made in the image of God relates to the Father, who cannot be contained by creation in accordance with scripture, chose to create beings in his own representation in creation, whereupon through his own representations, he express qualities of himself, one of which is authority, hence why even Adam, who was made in the image of God, was granted authority to rule over the earth, which relates to the greater authority granted to Jesus Christ, who is a higher image of God, which also relates to the authority that will be granted to the elect to rule on the earth, who are being conformed to the image of Jesus Christ. This authority, as representations of God, means to be like God, hence why we have an example of Moses being made "like God" and Aaron his prophet, because he was acting in representation of God having authority to bring forth powerful judgments against Egypt.
