At that moment Jesus said: My Father, Lord of heaven and earth, I am grateful that you hid all this from wise and educated people and showed it to ordinary people.
We do use wisdom when speaking to people who are mature in their faith. But it isn't the wisdom of this world or of its rulers, who will soon disappear.
The people were stubborn, and something still keeps them from seeing the truth when the Law is read. Only Christ can take away the covering that keeps them from seeing.
The god who rules this world has blinded the minds of unbelievers. They cannot see the light, which is the good news about our glorious Christ, who shows what God is like.
When we told you the good news, it was with the power and assurance that come from the Holy Spirit, and not simply with words. You knew what kind of people we were and how we helped you.
