Correct; being like something doesn't necessarily make one the other but this doesn't apply to God.
Matt 24:35
Heaven and earth will pass away, but My words will never pass away.
Heavens and earth represent everything that was created. If only God's word who is God shall not pass away, what is this other thing you are telling me that will not pass in the form of 'our immortal eternal- ever -after'?
It is the word of God that you willingly receive that will resurrect and live forever in the so called our immortal eternal ever after and it is God. The reason the Father and the son are one. It is the same word or spirit that God blew in Adam for him to be a living soul.
