1Cor. 1:25 Because the foolishness of God is wiser than men, and the weakness of God is stronger than men.
The wisdom of God is quite different from anything we have ever seen in this natural life. In some ways it all seems backwards. The first shall be last the humble are exalted. Salvation does not come because of our goodness, it actually comes despite our badness. Christ Jesus died for the ungodly and worse than that, He is said to justify the ungodly. Now don’t get me wrong. Paul didn’t teach an antinomian gospel. Not at all. Paul believed that we were saved by grace alone through faith alone but it didn’t stop there. We are actually changed by this grace so that our actions actually become Christ like. Now getting back to that wisdom thing, the gospel is actually the wisdom of God, there is no other way to be saved. Jesus was prophesied to be the Wonderful Counselor. Here is something John Calvin said of this prophetic title.
“The reason of this second title is, that the Redeemer will come endowed with absolute wisdom. Now, let us remember what I have just noticed, that the Prophet does not here reason about the hidden essence of Christ, but about the power which he displays towards us. It is not, therefore, because he knows all his Father’s secrets that the Prophet calls him Counsellor, but rather because, proceeding from the bosom of the Father, (John 1:18,) he is in every respect the highest and most perfect teacher. In like manner we are not permitted to get wisdom but from his Gospel, and this contributes also to the praise of the Gospel, for it contains the perfect wisdom of God, as Paul frequently shows. (1 Corinthians 1:24, 30; Ephesians 1:17; Colossians 1:9.) All that is necessary for salvation is opened up by Christ in such a manner, and explained with Prov. 18:10 The name of the LORD is a strong tower; The righteous run to it and are safe. such familiarity, that he addresses the disciples no longer as servants but as friends. (John 15:14, 15.)”
Jesus is actually the wisdom of God. Think about it, Christ is called the Word of God. He is actually the Father’s understanding or declaration of Himself as John said, John 1:18 “No one has seen God at any time. The only begotten Son, who is in the bosom of the Father, He has declared Him.” Jesus is the Father’s revelation of Himself therefore He is the wisdom of God. Jesus is the greatest of all Counselors because He is the mind or wisdom of God. Everything that we need for life is found in Christ. If we need counsel about family, finances, business, or ministry He is what we need. Paul said that Jesus has become for us everything. He is our wisdom, our redemption, our justification, and our sanctification. He is truly all we need.
