1 Corinthians 2:6 (WEB)
We speak wisdom, however, among those who are full grown, yet a wisdom not of this world nor of the rulers of this world who are coming to nothing.
1 Corinthians 2:7 (WEB)
But we speak God's wisdom in a mystery, sir wisdom that has been hidden, which God foreordained before the worlds for our glory,
11 For who among men knows the things of a man except the spirit of the man which is in him? Even so, no one knows the things of God except God’s Spirit.
13 We also speak these things, not in words which man’s wisdom teaches but which the Holy Spirit teaches, comparing spiritual things with spiritual things.
1 Corinthians 2:14 (WEB) 14 - Now the natural man doesn’t receive the things of God’s Spirit, for they are foolishness to him; and he can’t know them, because they are spiritually discerned.
