All of us are children of God in the sense that we were made by God. God lovingly created the first humans and became their Father. Furthermore, Christianity teaches that we can become a “child of God” in a fuller, richer sense by putting our trust in Jesus. This doesn't make us God, but it does require us to believe that Jesus was and is fully man and fully God. When we do this we can be reunited to our Father and reflect His image as we were created to do.
With that being said, we are not God or Gods.
