1 Corinthians 2:16 (KJV 1900)
16 For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ.
Who hath known the mind of the Lord…? There are two kinds of people, the natural man (natural = psyche), and the spiritual (spiritual = pnuema). The psyche of man (where we get our word, psychology) tends to always lean toward the natural world, or the base things of life. When we depend on our psyche will will never know God’s will for our lives. An unbeliever searches for truth in his psyche, yet psychology will never lead anyone to the truth of the Spirit.
But what about believers in Jesus Christ? We have the mind of Christ. We know from previous verses that having this Christlike mind will be a problem for Christians. When we have the mind of Christ we can expect persecution, mocking, slander.
In other words, the natural man will be opposed to and will not like the spiritual man. Expect this opposition to Christlikeness to increase in the latter days.
