Romans 8:27 : And he that searcheth the hearts know-eth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God. God is the great heart searcher. He knows our lightest thoughts and purposes and the deepest longings of our hearts. But what is meant by the mind of the Spirit? Mind may refer to the intellectual faculty or to the mental disposition, or mood. It is foreign to Paul's line of reasoning to make mind of the Spirit refer to the intellectual faculty of the Spirit or to the mental disposition of the Spirit. Verse 6 may help us out "For the mind of the flesh is death but the mind of the Spirit is life and peace." "Mind of the flesh" is evidently the mental disposition, or mood, of the per-son dominated by the flesh--the disposition of mind produced by the flesh. And so the "mind of the Spirit" is the mental disposition, or mood, produced by the Spirit. All that the gospel contains stirs up in the heart of the honest believer feelings and aspirations that he cannot express in words. But God, the heart searcher, knows the mental disposition, the feelings, and aspirations thus produced by the Spirit. It is easy to understand Paul, if we understand him to mean that God, who searches the hearts, knows the mental disposition produced by the Spirit. It is probable that God searches the heart through the agency of the Holy Spirit; "for the Spirit searcheth all things, yea, the deep things of God" (1 Corinthians 2:10).
