Divine unction only comes to those who have kept themselves pure in heart and mind.
Without that unction, ALL of our sermons are mere dribble, no matter how eloquent, persuasive, or intellectual.
Only as we are endued with power from on high as we preach will lives be radically changed.
Stephen Olford said "Beloved, if you stand behind this holy desk and you're life isn't pure; if you're life isn't absolutely holy as far as you know it; if are not walking under an unclouded sky with the ungrieved, unquenched Holy Spirit in your life; then, my friend, you've absolutely blocked the message from any authority whatsoever," he said.
While I was at Stephen Olford's home years ago during his Institute on Biblical Preaching, (there were just a couple of us back then when he first started the Institute in Memphis in 1985), I remember his admonition concerning power.
He said, "Don't you think for a minute that being instant in season and out of season means that you can ask God for His anointing to preach when you need it on Sunday, if you haven't been living in power everyday."
I have tried to remember that on Monday as well as on Saturday, and have always asked my church to be in prayer for me.. We simply cannot afford to let down our guard for a moment. How many men will we see with their armor not on and them ending up on the shelf, with no power, doing no mighty works, preaching merely from the intellect, dispensing no life, with Ichabod written over the lintel of their sanctuaries.
The man of God is to be endued with power from on high as he lives his dedicated life. His prayer should be, "God, if I cannot live my life with a divine anointing to preach and witness to the unbeliever, then just go ahead and take me home now." Oh that men would tarry before God until the power comes. There have been nights when I have waited before God through the night, pleading with Him for power. Most Mondays are spent seeking God and asking for a refilling of His Spirit. I often feel spent after a day of ministering. Yes, we need a fresh anointing all the time. God gives us a fresh anointing. Send down the power from on high. Shake this place where we worship and let the glory of God fall! Send the fire! Wake the sleeping church. Save the deaf, dumb and blind. Open the eyes of those who are blinded by the god of this world. Free those who are shackled by sin. Raise those who are dead to God. These mighty works only happen as the man of God is anointed with the power of God.
Preach with power!
