Yes flesh and blood cannot, that is why it is said that one is to be born of water and of the Spirit, there is no more blood. Jesus WAS raised to life in HIS GLORY, raised incorruptible, and it is Jesus who is of the fruit of David’s loins, ACCORDING to the FLESH that he sits on his throne. Mortal flesh is weak, immortal flesh that has God’s Spirit of eternal life and God’s Spirit that gives us faith in God makes us of the SECOND ADAM (HUMAN) a heavenly human. God renews us, he doesn’t change us into spirit beings or some entirely knew creature, we were created to become humans in His image, hence why we see the words last Adam (father of the human race), and second man (anthropos —human).
