One might expect that any show about an angel of god who walks the Earth trying to help people would be heavy-handed and depressing. Highway to Heaven is neither. It's an uplifting show that showcases all the best aspects of religion and niceness. Unlike "Touched by an Angel" and the televangelist shows, HtH deals with whether a person is good, not whether they subscribe to the right religion. There is room in the definition of "good" to include businessmen, politicians, and former criminals. I'm a hardcore atheist and I still love this show.
In addition, the element of God's power is never used as a club. Jonathan has "the stuff," but never uses it until words and persuasion have failed. It almost makes one feel that with a little effort, they might do some good themselves in the world. Throw in the grainy mid-80s picture and you've got a wonderful bit of escapism to a world where just a little good will can move mountains.
