Contemporary worship is framed within a paradigm of encounter: we gather to sing and to meet with God. In fact, many scholars have remarked that in charismatic worship, singing is the place of encounter. It ought to be noted, however, that Christian worship has in one sense always been about an encounter, which historically was God meeting us in the bread and wine.
The paradigm of encounter is significant because encounter involves emotion. What we mean in modern worship when we say that we ‘encountered God’ is that we were able to truly express our hearts to Him and that we are somehow in a mysterious way able to experience His presence. Both expression and experience have emotional qualities to them. This is not to see that they are solely emotional; only that they include and perhaps even rely upon emotion in order to occur.
Worship isn’t all about emotion, but emotion should always be a part of it. Read the whole thing here.
