This the meaning I got for REPOSE from dictionary.com
To place (trust, for example): reposed all his hopes in the new cure.
The act of resting or the state of being at rest.
Freedom from worry; peace of mind.
v. re?posed, re?pos?ing, re?pos?es
To lay (oneself) down.
To rest or relax (oneself).
To lie at rest.
To lie dead: repose in a grave.
To lie while being supported by something.
So it means to be at peace while being supported by something whether that something is real or imagined. It also has the meaning of ?entrusting? or handing over. I think what we did when we where dubs was hand over our search and analysis of reality to the WTS. This is bought out in this Watchtower

OUR VIEW OF THE ?SLAVE?
We can benefit from this consideration. If we have once established what instrument God is using as his ?slave? to dispense spiritual food to his people, surely Jehovah is not pleased if we receive that food as though it might contain something harmful. We should have confidence in the channel God is using. At the Brooklyn headquarters from which the Bible publications of Jehovah?s Witnesses emanate there are more mature Christian elders, both of the ?remnant? and of the ?other sheep,? than anywhere else upon earth.
True, the brothers preparing these publications are not infallible. Their writings are not inspired as are those of Paul and the other Bible writers. (2 Tim. 3:16) And so, at times, it has been necessary, as understanding became clearer, to correct views. (Prov. 4:18) However, this has resulted in a continual refining of the body of Bible-based truth to which Jehovah?s Witnesses subscribe. Over the years, as adjustments have been made to that body of truth, it has become ever more wonderful and applicable to our lives in these ?last days.? Bible commentators of Christendom are not inspired either. Despite their claims to great knowledge, they have failed to highlight even basic Bible truths?such as the coming Paradise earth, the importance of God?s name, and the condition of the dead.
When a dud says It's "The Truth" this and "The Truth" that----"How long have you been IN THE TRUTH?" and "Since Bob left THE TRUTH we haven't spoken a word". And on and on and on.... what they are really meaning is ?how long have you been in REPOSE?
