There are few other tasks in the family of God that surpass shepherding Jesus' flock—which is what you as a leader are doing. As you prepare to lead—whether it is one session or an entire series—keep in mind that you are not alone. God knows everything about you, and he knew that you would be asked to lead your group.
It is common for all good leaders to feel unready to lead. Moses, Solomon, Jeremiah and Timothy were all reluctant to lead. But as he did for them, God promises to us, "Never will I leave you; never will I forsake you" (Hebrews 13:5).
Remember, you don't have to try to do this alone. Pray right now for God to help you build a healthy leadership team. If you can enlist a co-leader, your experience will be much richer.
This is your chance to involve as many people as you can in building a healthy group. All you have to do is call and ask people to help—you'll be surprised at the response.
