O Timothy, guard the deposit entrusted to you. Avoid the irreverent babble and contradictions of what is falsely called “knowledge,”
1 Timothy 6:20 · ESVView all translations

Paul ends his first letter to Timothy with a personal cry and a charge. God has placed a treasure in Timothy's hands to guard. Timothy must also turn away from a counterfeit — a "knowledge" that only sounds like knowledge.

The deposit

What is this deposit? One writer says plainly what it is and what it is not:

"The deposit" here, as in 2 Tim. 1:14, means the truth God entrusted through His chosen instruments. It is divine revelation given in words taught by the Holy Spirit. It is the pattern of sound words which Timothy heard from Paul among many witnesses. It is not the soul or its salvation. It is not the ministerial office. It is not even the grace of the Spirit. It is the perfect communication of what God is in nature, ways, relationship, and counsels.

William Kelly

Timothy held a place no one else held. But the charge does not die with him:

We may not overstep our measure or take up the special duties of that honoured colleague of the apostle. But we are just as bound, in our own place, to guard the truth now entrusted to our keeping. In these last days of deception and self-will, one thing is declared to be the tower of safety: to acknowledge and receive every scripture as inspired by God.

William Kelly

Weighed at both ends

A deposit implies a day of reckoning, and one writer finds the picture in Ezra:

The treasures brought from Babylon were weighed both before and after the journey to Jerusalem (Ezra 8:24-34), so that nothing would be missing. In the same way, we must expect a close check of everything entrusted to us. We must guard with zeal, and keep pure, what really belongs to God.

Why the babble is called "profane"

Why does Paul call this empty talk "irreverent" or "profane"? The word points back to a threshold:

The word is linked to a word meaning "a threshold," which anyone may tread on and make unclean. It stands in contrast to a holy place or shrine, which is fenced in and guarded from defilement. In the New Testament older translations always render it "profane." Three times it describes babblings or empty talk (1 Tim. 4:7; 1 Tim. 6:20; 2 Tim. 2:16).

Morrish Bible Dictionary

Knowledge falsely named

Older translations read "science falsely so called." One group had already taken that title for themselves:

As soon as God revealed the true knowledge of Himself, the adversary began working to corrupt it... The Greek word translated "science" here is the usual word for "knowledge." The earliest corrupters of the faith were known as the Gnostics, which means "the knowing ones." They took their title from this word. The Apostle John referred to them in particular in his letters.

F. B. Hole

The same writer draws out what "falsely called" implies, and applies it to our own day:

These words imply that a true science exists, in full harmony with revelation. They also state plainly that even 2000 years ago there was a wrongly-named science which opposed revelation. It was largely made up of the speculations of the philosophers. The wrongly-named science of today is much the same: partial knowledge, based on imperfect or inaccurate observations, mixed with a great deal of speculation, often of the wildest kind.

F. B. Hole

What it does to a soul

Such teaching is not dull. It flatters man, and it turns him away from ruin and grace:

Nothing undermines the power of the truth we confess more than allowing theories which flatter man and keep the creature busy. Such theories ignore or degrade God and His Son, and in the end they will be found to deny both... This falsely-named knowledge tries to fill the emptiness that unbelief always feels, because it does not really know God and His Son. It fills that space only with its profane ramblings and contradictions. It cannot face the hard fact that sin has ruined man completely. So it avoids the revelation of pure grace, and of a righteousness which is God's own and which can justify the ungodly.

William Kelly

There is a cost, and it falls hardest on people who once looked strong in the faith:

It is sad to know men loving darkness rather than light, because their deeds are evil. But there is a deeper sorrow over those who once seemed to run well, and then went fatally wrong about the faith. They are not only the victims of folly and evil. They also blindly dishonour the Name which is above every name.

William Kelly

Grace for the guarding

The instruction itself is simple, and the letter's last line supplies the strength for it:

Avoid the babblings, and AVOID the wrongly-named science just as much as the babblings. We shall need grace from God to do this. So the letter closes with the words, "Grace be with you."

F. B. Hole

Summary

- Deposit — What Timothy holds is not his salvation or his office. It is God's own revealed truth, handed to him to keep safe.

- Weighed — Temple treasure carried out of Babylon was weighed at both ends of the journey. Our trust will be checked in the same way, and nothing may go missing.

- Common — "Profane" means ground anyone may walk on, the opposite of a guarded holy place. Empty talk drags holy things down to that level.

- Misnamed — The word here is just "knowledge." True knowledge agrees with revelation. What Paul warns against wears the name without the substance.

- Missed — Theories that flatter man cannot face ruin by sin, so they never reach grace. Some who once seemed to run well went fatally wrong about the faith. God's grace is what keeps the rest of us.
