Because Change Is Scary
It's also really hard to change habits. We get so set in patterns of behavior that we repeat them without thinking. Even if we think about them differently, we still have a hard time applying it to our lives. It's just easier to stay the same because it's normal. The only way to really have an effect is to create a new normal. Change our thought and behavior patterns. Prayer, Meditation, Learning, Discipline, and Accountability all work together to transform.
Back to Fear, Rejection & Vision
Besides that, sometimes, the vision that God has given me doesn't make sense to me. I don't understand where the resources are going to come from. I don't see how people would actually believe in that direction for the church. I can hear people's voices in my head shooting it down already. It might cause a division. People might leave the church. People might quit giving. People might stage a coup to get things back to the way they used to be. (What's on your list of fears?)
Even So, Sharing The Vision Is Worth It
Casting the vision is worth it because the opposite of my fears could come true. The vision may cause unity. More people might come to church. People might give more financial support. People might be inspired to take on new ministries. Miraculous gifts might be provided. People's lives might be transformed.
