The Reluctant Left Hand of God

When God created the last of his angels he got distracted momentarilly. The result was the runt. Short, balding, wings asquew he was not what God intended. There was something about this angel though that God appreciated. He had the faith and love of a child. He also made quite a few mistakes. Lucky for him the mistakes usually took an interesting turn. The rest of the angels except for Gabriel get a little fed up with teachers pet.
When God has to go to report on the system under his control Satan decides to take the runt down a peg. The runt is run ragged and even Gabriel is as well. God is gone so long that Satan is convinced he's not coming back. When he decides to take over and proclaims himself God, Gabriel and the runt team up and fight. God returns and defends his rightful place with Gabriels and the runts assistance.
Gabriel is replaced as first angel and the runt is given his greatest dream. To become a human and live amongst them. Arriving below as a child of ten he lives with Joseph and Mary. He learns to be a carpenter and when they go into town to see the profits the runt scoffs at what they have to say. He sets the record straight and becomes the most sought after prophet. When one of the prophets sets the runts family home on fire the runt travels alone and preaches for the next ten years.
At his last stop he runs into Satan again who was cast out and is now advisor to Nebuchadnezzer. The runt is tortured and humiliated but never forsakes God to the point the people turn to God because of his faith. A humorous tale of faith and what angels are really like,
