Thomas has to concentrate, one foot, one foot, one foot in front of the other.  He closed his eyes and swallowed, head writhing in fear, he heard the voice of God in his head talking to the other sounds and voices...  Telling him salvation was on the other side, so he pushed forward, pushed hard and slow...  However, he did push, looking for a handle on the monolithic door he grasps it in a hand and pulls.
