This is a question that I hear constantly... How many announcements are appropriate from the platform?
Research shows that after two announcements, people generally stop listening.
But, even when we know the answer, churches still struggle when service time comes. We believe there are so many important things that "have to be said" during the service we can't control ourselves. I saw this visual and it made me think of what we do to ourselves too often... from the platform, from our web site, etc. when we try to say everything at once.
Tell one story at a time. Mixing multiple stories in a single setting is confusing. Create one setting for each big idea.
If you have to make more than two announcements, try to tie them together into one cohesive thought.
