"Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal. And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing. And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing." (1 Cor. 3:1-3)
Post Script: I believe that the revelatory gifts have ceased, I just wanted to make the point that Paul made to the Corinthian church. They had lots of 'spiritual gifts' but they needed a lot more 'spirituality.'
