Salvation is thru one man (Jesus Christ), not 8 men! (The GB)
John 10:27 - "My sheep listen to my voice; and they follow me." Acts 4:12 - "Salvation exists in no one else, for there is no other name under heaven given to men by which we must be saved.” Psalm 146:3 - "Don't put your trust in human leaders; no human being can save you."
