1 Corinthians 2:6-10

Yet we do speak wisdom among those who are mature; a wisdom, however, not of this age nor of the rulers of this age, who are passing away;

but we speak God’s wisdom in a mystery, the hidden wisdom which God predestined before the ages to our glory;

the wisdom which none of the rulers of this age has understood; for if they had understood it, they would not have crucified the Lord of glory;

but just as it is written: “Things which eye has not seen and ear has not heard, And which have not entered the human heart, All that God has prepared for those who love Him.”

For to us God revealed them through the Spirit; for the Spirit searches all things, even the depths of God.
