The writer of Proverbs said,
While he was writing to actual shepherds, the admonition is also applicable to spiritual shepherds. You are to know your flock: who they are, what gifts they have, what motivates them, and what the Lord is saying to them. This doesn't mean you must know everyone by name but you must set up a system of care where someone knows their name, hears their heart, and can share with you what the Lord is directing them to do.
Your work as a spiritual leader cannot be done from the pulpit or carried out on Sundays only. It must be a concerted effort to serve the people by empowering them with the power God has given you to care for their needs and encourage their growth. What plan do you have in place to help you hear from "your flock"? Are you interested? Do you use technology and social media to do so? Who can you enlist to help you know the condition of your flock?
