We read in the book of 1 Corinthians chapter 2verse 6-10:
1 Corinthians 2: 6-10
6 However, we speak wisdom among those who have reached maturity; but a wisdom not of this century, nor of the rulers of this century, which are disappearing, 7 but we speak wisdom of God in mystery, the hidden wisdom that, from before the centuries, God predestined for our glory; 8 the wisdom that none of the rulers of this century has understood, because if they had understood it they would not have crucified the Lord of glory; 9 but as it is written: things that the eye did not see, nor heard, nor have they entered into the heart of man, are the things that God has prepared for those who love him. 10 But God revealed them to us through the Spirit, because the Spirit searches everything, even the depths of God. Biblia de las Am茅ricas
The apostle Paul emphasizes in these verses about spiritual wisdom that has nothing to do with the wisdom of this century or with the kingdoms of this world, much less with ancient wisdom which they did not consider even the Lord Jesus to crucify him, Here he is talking about the wisdom that comes from above, the wisdom that discerns the things of the spirit.
Spiritual wisdom is the true nature of God's wisdom and is acquired by all those who have decided to seek God's direction in all their ways, this wisdom is acquired mainly among those who have reached maturity within the princes of God and not wise men of this century.
God has great and hidden things for us that can only be revealed through the spirit, because the spirit knows everything and scrutinizes it.
