According to Tom Rath in Strengths Based Leadership: Great Leaders, Teams, and Why People Follow, there are 4 reasons that people follow a leader, 4 needs that every follower has that a leader meets. They are:

1. Trust: Trust is everything for a leader, but especially for a pastor. Because we are dealing with people’s lives, hearts and souls and not merchandise like a company, trust becomes the pinnacle of leadership. The moment your followers stop trusting you, stop believing you, the game is over. Character and integrity take a lifetime to build, but can be lost in a moment. This is why boundaries are so important for a leader, this is why a leader must continually make sure he is putting the needs of the organization first instead of his own empire. This is why authenticity and being the same person in private as you are in public is so important.
2. Compassion: While compassion may not be high on the list of CEO’s, if you are a pastor, it is in your job description. To care for, love, serve, shepherd, celebrate and weep with those you lead. Pastors need to be available to those in their church, to listen, counsel, pray with and sometimes just to give a hug. People want to know that you care. This comes across in personal interactions, but also how you talk about others, especially in a sermon.
3. Stability: If you are a church planter, stability is difficult. Even if you are an established pastor, stability can be hard, especially if you are making changes or leading your church into the future. A leader must learn how to balance leading change and keeping things stable. Followers want to feel safe, secure and that the world will not fall in on them. As we were planting Revolution six years ago, several people left at once and when I asked why their answers essentially were, “Too much is changing, we aren’t sure if we’ll make it.” Most of those people have since come back, but followers want to know something will make it.  
4. Hope: No one likes a negative leader. Yes, it may sell books and run up blog stats if you spout out about how the world is ending or it has never been so sinful (before you say that be sure to read the book of Judges and 1 Corinthians). According to Gallup, the best leaders make their followers “feel enthusiastic about the future.” Leaders continually must be looking into the future and helping their followers see that the best is yet to come, even when it feels impossible. Not by painting rosy pictures that aren’t possible, your followers are too smart and will see through that. But to continually say, “If you follow me, if you stay with us, here’s where we’re going.”
