Please pray for me that I never serve what I have not partaken of myself. Also never expect others to taste and see that He is good while your lips smack of the world and your breath reeks of idolatry.
A man preacheth that sermon only well unto others which preacheth itself in his own soul. And he that doth not feed on and thrive in the digestion of the food which he provides for others will scarce make it savoury unto them; yea, he knows not but the food he hath provided may be poison, unless he have really tasted of it himself. If the word do not dwell with power in us, it will not pass with power from us. And no man lives in a more woeful condition than those who really believe not themselves what they persuade others to believe continually. The want of this experience of the power of gospel truth on their own souls is that which gives us so many lifeless, sapless orations, quaint in words and dead as to power, instead of preaching the gospel in the demonstration of the Spirit. – John Owen in The True Nature of a Gospel Church
