Christ became for us wisdom

We were on the life journey with Jesus when he was on earth, when he went to the cross and took us into death, and with him when he rose from the dead, and when he ascended into Heaven. He took fallen humanity with him.
Ephesians 1:4 He chose us in Him before the foundation of the world …13 In Him you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise,

HE LIVES IN US TO CONTINUE HIS JOURNEY WITH EACH ONE OF US WHO BELIEVE. (1Timothy 4:10)
John 14:23 Jesus answered and said to him, “If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him. He who does not love Me does not keep My words; and the word which you hear is not Mine but the Father's who sent Me… But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things…

1Corinthians 1:30. But of God you are in Christ Jesus, who became for us wisdom from God
The Corinthians were not pleased with Paul’s preaching, and Paul was disappointed in the Corinthians willingness to embrace his preaching of the cross. Their culture had influenced their attitude to serving God. They were transactional in their relationship with Deity of any kind, and it had confused their understanding of wisdom. The hybrid culture of Jewish religion and diverse Greek philosophies shaped their wisdom into an earthly wisdom (James 3:13). They competed over spiritual things, quarrelled at their Communion services, took one another to court, and generally behaved as natural rather that spiritual people. Having natural wisdom gives people control over organizing their lives. But the cross means letting go of that control.

1Corinthians 2:2 For I decided to know nothing among you except Jesus Christ and him crucified.
The cross is mentioned only eleven times in all of the epistles, and all of them by Paul.
It was another one hundred years before the cross was devotedly embraced as a symbol of Christianity.

1Corinthians 1:20 Where is the wise? Where is the scribe? Where is the disputer of this age? Has not God made foolish the wisdom of this world? For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe. For Jews request a sign, and Greeks seek after wisdom; but we preach Christ crucified, to the Jews a stumbling block and to the Greeks foolishness, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. Because the foolishness of God is wiser than men, and the weakness of God is stronger than men. 30. But of God you are in Christ Jesus, who became for us wisdom from God—and righteousness (Our alignment with God) and sanctification and redemption…
1Corinthians 2:14 These things we also speak, not in words which man's wisdom teaches but which the Holy Spirit teaches, comparing spiritual things with spiritual. But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned. But he who is spiritual judges all things, yet he himself is rightly judged by no one. For “who has known the mind of the Lord that he may instruct Him?” But we have the mind of Christ.

Paul explained having the mind of Christ in Philippians 2:5 …Jesus humbled himself and became obedient to the death of the cross. Jesus trusted the wisdom of his Father and we trust Jesus as our wisdom – like a master chess player who knows all the right moves. Paul yearned for them to love God and one another and reap the fullness of salvation of his gospel.
1Corinthians 2:9 “Eye has not seen, nor ear heard, Nor have entered into the heart of man the things which God has prepared for those who love Him.”
