I mostly an curious about the second half of the scripture: how are we sanctified through the truth? It reminded me of another scripture in John:

And ye shall know the truth, and the truth shall make you free. -John 8:32

In that chapter Christ elaborated a bit more on how that works:

Whosoever committeth sin is the servant of sin. And the servant abideth not in the house for ever: but the Son abideth forever. If the Son therefore shall make you free, ye shall be free indeed. -John 8:34-36

So in one sense, we are talking about Christ when we say truth. He is the truth, so we are sanctified through Him.

I am the way, the truth, and the life: no man cometh unto the Father, but by me. If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him.  -John 14:6

But then why didn't He just say, "they might be sanctified through me."? Then we would miss out on the connectedness of it all. We are taught that all truth is one great whole, so as we learn truth and live it, we come to know Him.

For you shall live by every word that proceedeth forth from the mouth of God. For the word of the Lord is truth and whatsoever is truth is light, and whatsoever is light is Spirit, even the Spirit of Jesus Christ. And the Spirit giveth light to every man that cometh into the world; and the Spirit enlighteneth every man through the world, that hearkeneth to the voice of the Spirit, and every one that hearkeneth to the voice of the Spirit cometh unto God, even the Father. And the Father teacheth him of the covenant which he has renewed and confirmed upon you... -Doctrine & Covenants 84:44-48

...my voice is Spirit; my Spirit is truth; truth abideth and hath no end; and if it be in you it shall abound. And if your eye be single to my glory, your whole bodies shall be filled with light, and there shall be no darkness in you; and that body which is filled with light comprehendeth all things. Therefore, sanctify yourselves that your minds become singe to God, and the days will come that you shall see him; for he will unveil his face unto you... Remember the great and last promise which I have made unto you; cast away your idle thoughts and your excess of laughter far from you.  -Doctrine & Covenants 88: 66-69

That is why we as members of His church are taught to be truth-seeking people. John A Widtsoe said:

Mormonism [is] a system of truth which includes all truth, which accepts all truth. . . . A system which leads its followers into a life-long pursuit of truth.  (Parrish, John A. Widtsoe, A Biography, 360.)

I get the feeling I could keep finding more and more on the subject (since truth has no end and all), but that will have to do for today.
