1 Corinthians 2:1-10 New King James Version (NKJV)
2 And I, brethren, when I came to you, did not come with excellence of speech or of wisdom declaring to you the [a]testimony of God. 2 For I determined not to know anything among you except Jesus Christ and Him crucified. 3 I was with you in weakness, in fear, and in much trembling. 4 And my speech and my preaching were not with persuasive words of [b]human wisdom, but in demonstration of the Spirit and of power, 5 that your faith should not be in the wisdom of men but in the power of God.
6 However, we speak wisdom among those who are mature, yet not the wisdom of this age, nor of the rulers of this age, who are coming to nothing. 7 But we speak the wisdom of God in a mystery, the hidden wisdom which God [c]ordained before the ages for our glory, 8 which none of the rulers of this age knew; for had they known, they would not have crucified the Lord of glory.
9 But as it is written:
“Eye has not seen, nor ear heard,
10 But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God.
