Question: Can Our Body Indicate God's Form?
You have given the logic that since we humans who have come from God have a form therefore God must also have form. But our form that we can perceive is the body not the actual self. Then how can it be said that since we have a form therefore God must have a form?
Answer: It Is Shaped After Our Spiritual Form
Just as the form of your shirt is modeled after the form of your body, the form of your body is modeled after the form of your eternal spiritual body. And since your spiritual body has form, we can understand that God also has form.
