Jesus sent the Holy Spirit to the apostles with a mission to reveal all truth.
John 16:13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
The apostles wrote that down by inspiration.
Ephesians 3:3 How that by revelation he made known unto me the mystery; (as I wrote afore in few words,
When we read it, we can understand the same message the apostles received.
Ephesians 3:4 Whereby, when ye read, ye may understand my knowledge in the mystery of Christ)
Scripture makes complete. Thus, Scripture must itself complete to accomplish this. I.e. “all truth” Jesus promised has been given in the scripture.
2 Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: 17 That the man of God may be perfect, throughly furnished unto all good works.
The faith has been once for all time delivered. Does it need to be revealed again?
Jude 1:3 Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.
Understanding this completed miraculous, revelatory work of the Holy Spirit; read:
1 Corinthians 13:8 Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.1 Corinthians 13:9 For we know in part, and we prophesy in part.1 Corinthians 13:10 But when that which is perfect is come, then that which is in part shall be done away.1 Corinthians 13:11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.1 Corinthians 13:12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.1 Corinthians 13:13 And now abideth faith, hope, charity, these three; but the greatest of these is charity.
The Spirit said prophecies, tongues and revealed knowledge will cease. The obvious question is when?
v10 when the perfect comes. what is the perfect here? The parts are revelations, so the perfect (complete) is composed of those parts.
The childhood described v11, seeing dimly v. 12 are both illustrations of the beginning of the Spirits work in revealing the Gospel piece by piece, letter by letter to the apostles. But when that completed revelation is given, then there is no more need for ongoing revelations.
Like a puzzle, once you place the last piece do you go back to the box look for more? No. It is completed.
The perfect, in context, is made up of the identified parts. This cannot be a reference to Christ, because when Christ returns there will be miracles anew (resurrection, world on fire, etc).
Thus, modern claims of miracles & revelations & prophecies find themselves unsupported by the Word of the Spirit.
