If you desire for people to follow you, you have to connect with them. The catalyst of your relationship with them at any level may very well have to be a result of your constant effort to associate with them. An unbeliever’s only basis for coming into the knowledge of truth may well be his relationship with his teacher/preacher.
Connect with them on a personal level. Find out what it is that interests them and try to find a common interest. Get to know them personally. Visit their home. Invite them to yours. Go places with them. Let them know you care for them on more than a Pastoral level. If they consider you to be their friend, they will support you much more than if you are only an authority to them.
Connect with them on a professional level. If he is a doctor, read a few books on the latest surgery procedures. If he coaches football, learn a bit about the game. If she is a teacher, talk education with her.
Connect with them in your preaching. Personalize your preaching. Major newspapers write their articles on the 6th grade educational level. Hence they are able to reach a broader audience than if they wrote them on the college level where most people may not understand certain wording. Bring bible stories and situations into present day circumstances. Touch home once in a while.
Connect them to others in the church. Without good relationships in the church, new converts do not stay. If a person has only a few people they are connected with in the church, their chances of staying are much higher than someone who does not find relationships within the church. Create ministries to get them connected.
