Have each person write out their schedule.
If the circumstance is a one-time meeting with no expectation of follow-up, then suggest a detailed calendar for the next week. For longer lasting mentoring or prayer partner arrangements, it will be good to add a “usual” current weekly schedule.
Pair up and exchange schedules. Ask a few questions and then pray through the other person’s agenda. Encourage everyone to take their partner’s list home and pray regularly for the events of the day.
