If you’re in Christian leadership, its your job, your responsibility, to keep asking and encouraging people to give their time and effort to ministry. So much so, that it can feel like every interaction and phone call is a request.
On one hand, you have to be ok with that. If you don’t call people to step up to do the good works God has prepared them to do, there’s a good chance they won’t. Thank God for your role of getting people on the ministry field.
On the other hand, it gives you a great opportunity to surprise people with the opposite. Just call to say hi. Chat. When they ask what you’ve called them about (as they probably will) just say, “No reason. I realised that almost every time we’ve chatted has been about something that needs doing, so I just thought I’d call and say hi. That ok?”
