The idea of royalty is found throughout different spiritual traditions. Jesus is said to be the King of Kings, the Buddha talks of noble and ignoble peoples (essentially, those who are on the path to awakening, and those who aren't).
When one sees that one is a child of God, made in His image, one sees that all have a kind of nobility to them. Mind you, this doesn't mean we always act in accordance with this. We screw up, we falter, we stumble.And that's fine. Part of the plan and the learning process really.
Just remember to get back up again and keep walking.
