Holding on to the past

According to all known Vampire lore, the blood draining subjects of Lucifer, called vampires, melt in the holy light of God and when they come in contact with the holy symbol of the Lord, the cross. Naturally most people who become vampires either turn away from their past life and except themselves as vampires and adopt to their new life. Except for one. Zakariah Preston. He is still holding on to his old life and his dedication to his faith has attracted both god and Lucifer to him. One saying to keep his faith and the other to forget about the past. What will he do?
