If you lead a small group of any kind, I highly recommend reading Jonathan Dodson's entire series on how to have gospel conversations.  Very helpful stuff! Part 1 Part 2 Part 3

Here's one section by Dodson that I think is key to leading well:

Be a Lead Repenter. It is important that the leader be a “lead repenter” when answering heart-penetrating questions. This does not mean you are always the first to answer the question; however, it does mean that you come to the gathering ready to share how the Spirit has lead you into repentance in your own life. Lead repenting begins at home in your heart and naturally carries over in how you lead during gatherings. Be bold with your brokenness and invite words of correction and encouragement.
