I will share my understanding. Little respect to the worship (includes everything) is mainly depends on two things.
1. Lack of Knowledge or Holiness of the participant
2.Testimony of the assigned person (Leader of the service)
First point- everyone have to examine themselves in the presense of the Lord
To explain second point- I would like to share a story...Once there was an Evangelist...preaching in a market place about Jesus Christ and his Ressurrection. People gathered around him to hear from him. After 5 minutes a magician arrived there and started showing magic. Then the people around Evangelist moved to him one by one. At last there was no one to hear from the evangelist. After the program magician has got lot of money. At last only the Magician and Evangelist left there, then the Evangelist approached the magician and asked him what is his secret of attracting people. He replied, The people knows that what I am doing is not real. But I present it as if it is a real one. But in your case whatever you are saying is fact but you present it in a way that it never happened.
If I know Jesus personnally, I could present him in that way. Otherwise what ever I am doing will be simply actions. Let us try to know Jesus more and more (than 'about Jesus')
