1 Corinthians 2:12-14

But God has given us his Spirit. This is why we don't think the same way that the people of this world think. This is also why we can recognize the blessings God has given us. Every word we speak was taught to us by God's Spirit, not by human wisdom. And this same Spirit helps us teach spiritual things to spiritual people. This is why only someone who has God's Spirit can understand spiritual blessings. Anyone who doesn't have God's Spirit thinks these blessings are foolish.
