Is there any difference between the morning and evening service?
Yes.
Although the format of each service is substantially similar, a time of corporate worship and a 40-50 minute message, each has its own distinctive flavour.
The morning services are more formally structured (although with the same informal worship style) with a 40-50 minute message based on a theme or topic from the bible (for example, the cross, prayer, faith). The evening tends to be loose in terms of structure, with a 40-50 minute expository message working systematically, week-by-week through a book of the Bible. The evening service tends to finish with an extended time of corporate worship.
