I think what truly made the lesson great was that we had some amazing members with us that could help explain how the gospel has blessed their family. What they said was just what the family needed to hear. We were concentrated on getting them to feel the Spirit. When you forget about yourself, how well you're teaching, and what others may think of you, and you focus completely on what the investigators need (which is the Gospel) and what the Spirit is telling you, it's amazing what difference it makes! You truly feel the love God has for His children, and you feel the overwhelming desire to help them find the blessings that come from living the commandments of God.
