One of the key challenges that Church Planters face is communcating their vision with the goal of raising partners, most of whom will never regularly attend the church that is being planted.
A couple of thoughts that have been very helpful to me:
1. Be clear about the gospel vision that Jesus is calling you to.
2. Pray and ask God bring partners with a heart for His vision.
3. Identify the relationships God has placed around about you:
4. Get in touch with them, communicate the vision and ask them to prayerfully consider partnering with you.
