An important aspect of faith is being taught here. It is one thing to believe "in" a Jesus that has your ticket to heaven. It is another to believe to the point of His Lordship in your daily life; to believe to the point of knowing and obedience. It is the test of true love.
This is a partial list of the Comforter's responsibilities. These abilities had until now only been shadowed in OT prophets. The HolyGhost is crucial to the believer in order to know and conduct daily relations, therefore obedience to our Lord.
