“1 And I, when I came to you, brothers, did not come proclaiming to you the testimony of God with lofty speech or wisdom. 2 For I decided to know nothing among you except Jesus Christ and him crucified. 3 And I was with you in weakness and in fear and much trembling, 4 and my speech and my message were not in plausible words of wisdom, but in demonstration of the Spirit and of power, 5 so that your faith might not rest in the wisdom of men but in the power of God.
6 Yet among the mature we do impart wisdom, although it is not a wisdom of this age or of the rulers of this age, who are doomed to pass away. 7 But we impart a secret and hidden wisdom of God, which God decreed before the ages for our glory. 8 None of the rulers of this age understood this, for if they had, they would not have crucified the Lord of glory.
9 But, as it is written, “What no eye has seen, nor ear heard, nor the heart of man imagined, what God has prepared for those who love him”—
10 these things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God. 11 For who knows a person’s thoughts except the spirit of that person, which is in him? So also no one comprehends the thoughts of God except the Spirit of God. 12 Now we have received not the spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God. 13 And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who are spiritual.
14 The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned. 15 The spiritual person judges all things, but is himself to be judged by no one. 16 “For who has understood the mind of the Lord so as to instruct him?” But we have the mind of Christ.
1 Hear this, O house of Jacob, who are called by the name of Israel, and who came from the waters of Judah, who swear by the name of the LORD and confess the God of Israel, but not in truth or right.
2 For they call themselves after the holy city, and stay themselves on the God of Israel; the LORD of hosts is his name.
3 “The former things I declared of old; they went out from my mouth, and I announced them; then suddenly I did them, and they came to pass.
4 Because I know that you are obstinate, and your neck is an iron sinew and your forehead brass,
5 I declared them to you from of old, before they came to pass I announced them to you, lest you should say, ‘My idol did them, my carved image and my metal image commanded them.’
6 “You have heard; now see all this; and will you not declare it? From this time forth I announce to you new things, hidden things that you have not known.
7 They are created now, not long ago; before today you have never heard of them, lest you should say, ‘Behold, I knew them.’
8 You have never heard, you have never known, from of old your ear has not been opened. For I knew that you would surely deal treacherously, and that from before birth you were called a rebel.
9 “For my name’s sake I defer my anger; for the sake of my praise I restrain it for you, that I may not cut you off.
10 Behold, I have refined you, but not as silver; I have tried you in the furnace of affliction.
11 For my own sake, for my own sake, I do it, for how should my name be profaned? My glory I will not give to another.
12 “Listen to me, O Jacob, and Israel, whom I called! I am he; I am the first, and I am the last.
13 My hand laid the foundation of the earth, and my right hand spread out the heavens; when I call to them, they stand forth together.
14 “Assemble, all of you, and listen! Who among them has declared these things? The LORD loves him; he shall perform his purpose on Babylon, and his arm shall be against the Chaldeans.
15 I, even I, have spoken and called him; I have brought him, and he will prosper in his way.
16 Draw near to me, hear this: from the beginning I have not spoken in secret, from the time it came to be I have been there.” And now the Lord GOD has sent me, and his Spirit.
17 Thus says the LORD, your Redeemer, the Holy One of Israel: “I am the LORD your God, who teaches you to profit, who leads you in the way you should go.
18 Oh that you had paid attention to my commandments! Then your peace would have been like a river, and your righteousness like the waves of the sea;
19 your offspring would have been like the sand, and your descendants like its grains; their name would never be cut off or destroyed from before me.”
20 Go out from Babylon, flee from Chaldea, declare this with a shout of joy, proclaim it, send it out to the end of the earth; say, “The LORD has redeemed his servant Jacob!”
21 They did not thirst when he led them through the deserts; he made water flow for them from the rock; he split the rock and the water gushed out.
22 “There is no peace,” says the LORD, “for the wicked.””
(1 Corinthians 2:1–16; Isaiah 48:1–22 ESVi)
