Just the other day I received a referral by way of the Holy Spirit. I was sitting in my car we working on Sundays sermon. I heard this truck trying to start over and over again. The Holy Spirit said go ask the people if they want you to pray for their truck. So I obeyed the leading of the Spirit. The people welcomed my offer to pray. As the driver of the car turned the key and their truck started, she said "Thank you Jesus." That is the best kind of referral when God leads things happen.
