Jett did a great job in his explanation. Remember in Genesis when God says "Let us make man in our image". Mankind is in the image of God. This means that God has two arms, two legs, two eyes, etc. and looks exactly like us. Our spirits also have the shape and form as a man's body, however our spirits are not flesh and are not tangible. this makes sense since God is the father of our spirits and we are his offspring.
