Servant-thinking is humble, acknowledging that God is sufficient. Servant-thinkers will look for His grace in their weaknesses; they do so because they think Theocentrically. Biblical, that.

And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. 2 Corinthians 12:9

“Both Lutherans and Calvinists answered the question ‘What must I do to be saved?’ by saying that Spirit-worked repentance toward God and faith in the Lord Jesus Christ and His substitutionary work of atonement are necessary. But Lutherans had a tendency to remain focused on the doctrine of justification, whereas Calvinists, without minimizing justification, pressed more than Lutherans toward sanctification, which asks, ‘Having been justified by God’s grace, how shall I live to the glory of God?’” (Joel R. Beeke, Living for God’s Glory: An Introduction to Calvinism, p. 11).

A servant-thinker is one who “adopts God’s world as his own.”[1] Therefore, “the believer [servant-thinker] . . . is affirming creation as it really is; he is accepting creation as the world that God made, and he is accepting the responsibility to live in that world as it really is.”[2]

“To be a creature is to be limited in thought and knowledge, as in all other aspects of life. We are limited by our Creator, our Lord. We have a beginning in time, but He does not. We are controlled by Him and subject to His authority; we are the objects of ultimate covenant blessing or cursing, and so the nature of our thought should reflect our status as servants. Our thinking should be ‘servant-thinking’” (John Frame, The Doctrine of the Knowledge of God, p. 21).
