1 Corinthians 2 - Those steeped in Judaism are no different today. 2016

1 Cor 2:11
For who among men knows the thoughts of a man except the spirit of the man, which is in him? Even so the thoughts of God no one knows except the Spirit of God.

The things of Elohim are revealed through the Spirit. It is not of our own intellect or insight. The understanding of Scripture does not come from us, but from the Spirit of Elohim alone.

1 Cor 2:12
Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things freely given to us by God,

1 Cor 2:13
which things we also speak, not in words taught by human wisdom, but in those taught by the Spirit, combining spiritual thoughts with spiritual words.

Wisdom of Elohim does not come from human wisdom. It is only taught by the Spirit, combining spiritual thoughts with spiritual words. Wisdom and insight into the Word of Elohim will come through the Spirit to those who are chosen.
