Weekly Thoughts 

It may be that the group has within it, someone, or even a team of people, who can write a weekly (or possibly daily) 'thought', based on a Bible passage. These 'thoughts' need not be long, but would normally take some Bible verses and apply them to the workplace context perhaps bringing encouragement into issues that the organisation may be facing. Here's a simple example.

Alternatively, there are many sources of daily thoughts on the web. Some of these could be adapted to be used within the group. Some people are very appreciative of a Bible-based inspirational comment as they start their working day.
