Praise and Worship is very important, that we do not make up are own rules how we do it because we must worship him spirit and truth.

Joh 4:23  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  Elohim is a Spirit: and they that worship him must worship him in spirit and in truth.

What is the opposite of truth is a lie some times we don't think about it in that way, not only dose he give us times when we are supposed to get together the (moedim) to worship Him. But in how it is very important that  we do not have sin in the camp I am not saying that I am perfect but we need to be blameless
and make things right before we enter the holy of holies
