My initial thoughts about this new tower were that it was a good picture of our prayers piercing the heavens so that God could hear our petitions. However after further thought, I would suggest that God is the one who opens the heavens and is eagerly waiting and seeking our prayers. We don't need to exert lots of effort in breaking through - sometimes it's necessary but generally God's eyes are searching for those that are faithfully seeking his face, his voice, his way.
