There is no better evangelist in the world than the Holy Spirit.
Dwight L. Moody
The Holy Spirit is part of the Trinity and part of God. He has nothing contrary to say about the Word or God.
If someone does something or is teaching something other than the Word of God and says it’s from the Holy Spirit, they’re being deceived. Jesus went to be with the Lord so he could send back the Comforer.
John 16:7 – 7 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you. KJV
John 16:7 – 7 Nevertheless I tell you the truth. It is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I depart, I will send Him to you. NKJV
John 16:7 – 7 But I tell you the truth: It is for your good that I am going away. Unless I go away, the Counselor will not come to you; but if I go, I will send him to you. NIV
Counselor, Helper, Comforter, the Holy Spirit is all those things and our communication line to the Lord. There is no better evangelist.
