You can tell a lot about a person by the way they worship God. Some people worship because they have been taught to. Some because they are going through the motions.
Then you have the heart felt worshipers. The ones that worship with all of their heart. You can feel the love that they have for their God.

 But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.
²⁴ God is a Spirit: and they that worship him must worship him in spirit and in truth.
