I Corinthians 2:4

Behold, are not all these which speak Galilaeans?

Jesus, . . . saw two brethren, . . . casting a net into the sea: for they were fishers. And he saith unto them, Follow me.

I believed not the words, until I came, and mine eyes had seen it; and, behold, the half was not told me.

The queen of the south shall rise up in the judgment with this generation, and shall condemn it: for she came from the uttermost parts of the earth to hear the wisdom of Solomon; and, behold, a greater than Solomon is here.

Paul was a scholar and an orator of the first rank; he is not speaking out of abject humility; but saying that he would veil the power of God if, when he preached the gospel, he impressed people with his "excellency of speech."

Belief in Jesus is a miracle produced only by the efficacy of Redemption, not by impressiveness of speech, not by wooing and winning, but by the sheer unaided power of God.

If in preaching the Gospel you substitute your clear knowledge of the way of salvation for confidence in the power of the Gospel, you hinder people getting to Reality. You have to see that while you proclaim your knowledge of the way of salvation, you yourself are rooted and grounded in faith in God. Never rely on the clearness of your exposition, but as you give your exposition see that you are relying on the Holy Spirit. Rely on the certainty of God's redemptive power, and He will create His own life in souls.

When once you are rooted in Reality, nothing can shake you. If your faith is in experiences, anything that happens is likely to upset that faith; but nothing can ever upset God or the almighty Reality of Redemption; base your faith on that, and you are as eternally secure as God. When once you get into personal contact with Jesus Christ, you will never be moved again. That is the meaning of sanctification. God puts His disapproval on human experience when we begin to adhere to the conception that sanctification is merely an experience, and forget that sanctification itself has to be sanctified (see John 17:19). I have deliberately to give my sanctified life to God for His service, so that He can use me as His hands and His feet.
