1 Cor 2:16 is a quotation from the book of Isaiah 40:13 where Paul uses "Mind" for "Spirit"; and both are identical in God Almighty. The will of God, the ways of God, and the word of God are one
No one can know the things of God including the mind of the Lord without the Spirit of God.
As Christian believers, we have been sealed with the Holy Spirit of Promise which is the proof that we have the mind of Christ
1Corinthians 2:16
