> If it actually went over their heads, then the effort was wasted. I've heard the goal of preaching described thus: "Address the mind to move the heart to change the will." If you haven't addressed the minds of the people you're speaking to, your preaching was a failure.

Reminds me of Pauls retort about speaking in tongues with no translator. ;)

The idea being, that if it serves nobody but the person themselves, they should keep it to themselves, if you're going to "share" with the whole congregation, then it should edify the congregation.

1 Corinthians 14:27-28 (KJV)

"27 If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret.

28 But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God."
