Wherever My followers go, there should be My Light surrounding them. The Light of the Sun of Righteousness.
Evil cannot live in that Light.
Man is only just learning that light banishes disease.
Every follower of Mine who is in close personal touch with Me is surrounded by this Light. Light Eternal. Light reflected by a consciousness of My Presence.
So whether he speak or not he must be the means of diffusing My Light wherever he goes.
