1 Corinthians 2:16 For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ.
The mind of man
The Bible mentions several aspects of the mind – reprobate mind (Ro 1:28), carnal mind (Ro 8:7) and a defiled mind (Tit 1:15). It speaks of those who “walk in the vanity of their mind” and “blindness of the mind” (Eph 4:17-18).
When a person is born again he/she becomes a new creature in Christ and begins the work and life of renewing their mind so that they might not follow the world’s way of living (Ro 12:1-2).
Knowing the mind of the Lord
Paul echoed the same thing in Ro 11:34 probably quoting from Isa 40:13 when he wrote it. It is an interesting question very much different from us today who can literally know what another is thinking – husbands and wives.
There are many aspects to God’s infinite mind, but the key is undoubtedly the attribute of sacrificial love (Phil 2:5-6, 8). So following His example we should be of a humble mind: not to think of our self beyond what we are (1 Cor 10:33 – 11:1; Ro 12:3; Gal 6:3).
In Lowliness of mind (Phil 2:3) in our relations to others.
Remember the suffering of Christ when we go through persecution or suffering as a Christian (Heb 12:3).
Be ready to receive the word as the Spirit relays it to us -- readiness of mind (Acts 17:11) – readiness means eagerness, willingness. There are many that hear the word and doubt it because they are unwilling to obey it or because it contradicts their philosophy or idea of life and being Christian.
Serve the Lord with all humility (Acts 20:19) that when He accomplishes good or great things thru us as yielded vessels we will remember that we are simply a pen in the Master’s hand (2 Cor 12:7-10; 3:5; 1 Cor 15:9-10).
