It always amazes me when men think they can teach men for the ministry better than Jesus Christ.
John 16:13-14 " 13 However, when the Spirit of truth comes, He will guide you into all truth. For He will not speak on His own, but He will speak what He hears, and He will declare to you what is to come. 14 He will glorify Me by taking from what is Mine and disclosing it to you.…"
Isaiah 11:2
John 14:17
"the Spirit of truth. The world cannot receive Him, because it neither sees Him nor knows Him. But you do know Him, for He abides with you and will be in you."
Notice that when it is the Holy Spirit Who teaches men, it is God Who is glorified not man.
