They believe they can learn from you and grow under your ministry. (Matt 4:19). All leaders want to grow. It's hard to sit under someone who is a poor leader, or someone who has stopped growing and fallen behind you in their development. You must keep growing yourself. As you keep growing, the kind of leaders you will attract will get better. Make sure, when they do come, that you're not threatened or intimidated by them.
There is opportunity for promotion if they perform well. It's important to have small groups and new church plants because they give leaders the opportunity to demonstrate their leadership skills. They can grow from being a leader of 5's to 10's, 50's, 100's, and 1000's according to the Exodus 18 Principle. It's important to have a list of potential leaders and a list of potential positions always in mind. A well-designed flow chart can help make this visible to others. As you pray over these lists and give thought to both the people and the positions, you'll be amazed how God will reveal where people fit best. Maximum fit = minimum stress.
You have a big vision. Big vision attracts, builds, and releases big leaders. President De Gaulle said to Winston Churchill, "If you do big things you will attract big people; if you do little things, you'll attract little people and little people will cause you lots of problems." Leaders will ask themselves, "Is there room enough in this church and this movement for my calling and giftings?" Give your people a challenge that will stretch them. "Attempt great things for God, expect great things from God" (William Carey).
They see an environment that is challenging, creative, and flexible, along with order and good leadership. Don't be afraid to ask leaders for commitment. If you don't, you'll lose people; and if you do, you'll lose people. It all depends on which group you want to keep and which group you want to lose. If you ask for commitment, you'll keep the winners and lose the whiners. The choice is yours - choose life!
Yours for a vision that goes far beyond this life!
