Thanks much to Of First Importance for this:

“The gospel . . . is the wisdom of God because it doesn’t praise our intellects or advertise our strengths. It causes us to fall on our knees and acknowledge our weakness, our dependence, our terrible need. It causes us to look up to God as the great Savior. ‘It is by his doing that we are in Christ Jesus’ . . .. The gospel teaches us that our righteousness, our sanctification, our redemption, and our wisdom are all gifts of God. The message of the gospel scuttles human pride because it reminds us that our life did not start with our choosing God but his choosing us. Therefore, all the glory is God’s.”
