The Holy Spirit reveals the "things freely given to us by God." Human ingenuity and intellect cannot penetrate God's mind or wisdom. It must be revealed to us. Paul doesn't say the Holy Spirit helps us to understand the things of God; he says that the Holy Spirit is essential to understand the things of God. To the church, God gives the Spirit, who is like a shy sovereign. He doesn't want to be the centre of attention; his true task is to shine the spotlight on Jesus Christ and the glorious blessings we have through his crucifixion.
