God Speaks Through the Bible
(not through prophets as in times past)

Hebrews 1:1-2 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;

That God spoke directly to prophets in "time past" is affirmed by the Hebrew writer. But the same writer informs us that God changed the way he speaks to man. In "these last days" he has "spoken unto us by His Son." The last days did not begin until after the death of Christ (Acts 2:16-17). The Lord did speak audible while on earth, but the words he spoke that God chose to be recorded for us are found in the New Testament. Also, Christ inspired certain ones to write letters to churches that would be part of the teachings of Christ that we are to "hear" as we read them. We are hearing the words of Christ as he speaks to us through the apostle's teachings. The apostle Paul wrote: "If any man think himself to be a prophet, or spiritual, let him acknowledge that the things that I write unto you are the commandments of the Lord" (1 Cor. 14:37).

The revelation from God has been "once delivered to the saints" (Jude 3).

This means He is not still revealing things to people other than through the Bible.

Titus 1:9 He must hold firmly to the faithful word as it was taught, so that he can encourage others by sound teaching and refute those who contradict it.

The word has been taught and must not be contradicted with new revelations. God has spoken and no man has a right to add to or take away from what is written.

Revelation 22:18-19 For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.

Titus 2:1 But as for you, speak the things that are consistent with sound doctrine.

"Sound doctrine" has been established. It is the New Testament. Speaking things someone has proclaimed to have heard from God is to add to God's word.

2 Thessalonians 2:15 "Therefore, brothers, stand firm and cling to the traditions we taught you, whether by speech or by letter."

The apostles taught in two ways, speech and letter. God chose them to teach in these ways and there is no indication in the New Testament that God teaches in any other way after the New Testament was complete and made available.

1 Corinthians 13:8-13 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. For we know in part, and we prophesy in part. But when that which is perfect is come, then that which is in part shall be done away. 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. 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. And now abideth faith, hope, charity, these three; but the greatest of these is charity.

There should be no doubt as to what "that which is perfect is come" refers to. Jesus has already come, so it cannot be Him to which it refers. The context is knowledge - it was "in part" because the gospels and letters to the churches were not together in one place. Thus, people could only "know in part" but after it is available man could then know Him, even as people knew Paul whom they had met face to face.
