To make a fire tunnel we make two lines of spiritual leaders like pastors, special guests, and prayer team members. Then we have everyone line up and walk between the lines. During this time we lay hands on each person so that each person gets prayed for and has hands laid on them by many powerful people.
"For this reason I remind you to kindle afresh the gift of God that is in you through the laying on of my hands."
2 Timothy 1:6
"For I long to see you that I may impart some spiritual gift to you, that you may be established."
