One of the problems (among many) facing churches who do not welcome the Holy Spirit's presence is this: when preachers or teachers share - when people hear wisdom or (hopefully) revelation from anyone  - if the Holy Spirit isn't present when it's shared - if He isn't the one who is sharing  - it avails us nothing.

He is the one (the only one) who can impregnate us with THE WORD - planted deep in the soil of our hearts. Without Him, it won't take root inside us and bear fruit  - it will merely pass through our minds. Oh, we may remember some of it. It may be delivered to us with polish and style. Our favorite speaker may do a wonderful job - but if it only impacts our minds and not our hearts - it avails us nothing (eternally). 

We become parrots of our favorite preacher or teacher until we let the Holy Spirit, deep within, he can't expound upon and expand what is being shared, and he can't weed out what is not of Him thereby protecting us from false doctrines and the pet traditions of men  -  revealing to us God's heart and His ways instead, which are usually the complete opposite of man's.  

Much of the teaching from pulpits around the world are teachings swallowed in a Bible school or Seminary, then regurgitated for the masses. It's too often pap - prepared for babies, which is what the people often are. Men are instructed by other men, then they in turn instruct others, on and on, until Christ returns. Without the Holy Spirit the cycle never ends  - he alone can seperate falsehoods from truth, he alone can "lead us and guide us into all truth" and prevent us from making clones of one another.
