The truth was in Gaius, and Gaius walked in the truth. If the first had not been the case, the second could never have occurred; and if the second could not be said of him, the first would have been a mere pretense. Truth must enter into the soul, penetrate and saturate it, or else it is of no value.
Doctrines held as a matter of creed are like bread in the hand, which provides no nourishment to the body; but doctrine accepted by the heart is like food digested, which by assimilation sustains and builds up the body.
In us truth must be a living force, an active energy, an indwelling reality, a part of the warp and woof of our being. If it is in us, we cannot then part with it.
A man may lose his clothes or his limbs, but his inward parts are vital and cannot be torn away without absolute loss of life. A Christian can die, but he cannot deny the truth.
Now it is a rule of nature that the inward affects the outward, as light shines from the center of the lantern through the glass: When, therefore, the truth is kindled within, its brightness soon shines in the outward life and conversation.
It is said that the food of certain worms colors the cocoons of silk that they spin: And in the same way the nutriment upon which a man's inward nature lives gives a tinge to every word and deed proceeding from him.
To walk in the truth conveys a life of integrity, holiness, faithfulness, and simplicity--the natural product of those principles of truth that the Gospel teaches and that the Spirit of God enables us to receive.
We may judge the secrets of the soul by their appearance in the man's behavior. Today, O gracious Spirit, let it be ours to be ruled and governed by Your divine authority, so that nothing false or sinful may reign in our hearts, in case it should extend its malignant influence to our everyday lives in the community.
