1 Corinthians 2:10, 14
1 Corinthians 2:10 ASV
But unto us God revealed them through the Spirit: for the Spirit searcheth all things, yea, the deep things of God.
1 Corinthians 2:14 ASV
Now the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him; and he cannot know them, because they are spiritually judged.
