Jonathan Smith

Jonathan Smith, formerly a man who lived on Earth named Arthur Thompson, is now a "probationary" angel sent to Earth to help people in need. In the course of an "assignment," he meets Mark Gordon, an embittered retired policeman now bouncing from job to job. At first distrustful of Jonathan, Mark helps him complete his assignment and soon comes to realize his true nature, and is then given a job by "The Boss" (i.e. God): to assist Jonathan in helping troubled people on Earth. Jonathan and Mark are given assignments where they help various troubled souls overcome their problems.

Each episode typically begins with Jonathan and Mark arriving in a new city and taking jobs as business employees or civil service workers as part of their latest assignment. Due to Jonathan's angelic nature, the two can work as police officers, medical personnel, teachers, social workers or other skilled employees (background checks or employment history verification being "angelically" provided or somehow never looked into), allowing for a variety of identities and scenarios. Both Jonathan and Mark face the same difficulties as people on Earth trying to rectify these problems, and have little to aid them beyond a bare outline of their assignment. Jonathan has exceptional physical strength, but he can only use it for manual labor or self-defense. At certain times Jonathan presents gifts to others, such as decorating a drab nursing home with flowers or giving someone a bicycle. These material gifts likely come from "the Boss" or Jonathan's superiors, but when asked, he answers only "A friend of mine provided them." However, in rare situations, "The Boss" provides the protagonists with what Mark calls "The Stuff" (i.e. divine intervention).

He revealed to Mark that when he was human, he died of lung cancer.

In the episode "To Touch the Moon" Jonathan reveals that he trained at Nasa with Gordon Nealy...its undetermined whether this was as an Angel or while he was alive

In the episode, "The Secret" he went against God's wishes and interfered causing him to return back to Heaven.

In the episode "Keep Smiling", it is revealed that when he was alive, his name was Arthur Thompson and that he has to help his wife move on.

As a child, Arthur (Jonathan) had a dog named Ike; he named him after President Eisenhower.

Jonathan is left-handed and shorter than Mark.

Powers
He can teleport and goes into buildings without much effort or resistance. He has "the stuff" as Mark Gordon affectionately calls it. When Jonathan goes on his own accord, God will not give him help.

He has demonstrated manipulating the elements around him. A popular example would be when Mark tries to play country music on the car radio. Jonathan would turn it off.

Jonathan has also shown that he can turn himself into other things. For example, in " Man's Best Friend", he turns himself into a lion to scare off some coyotes.

At times, God will help him with certain tasks or make suggestions.
