"Give me the reins." I'll always remember when the Holy Spirit spoke those four words to my heart. It was clear He wasn't asking for one "rein" he wanted all my "reins."
Of course, I immediately thought of a horse's reins. The rider uses the reins as a restraining influence to control the animal with his guiding power. That example coupled with Scripture offered me insight into what the Holy Spirit meant—and delivered me into a new level of freedom in Christ.
When David invited Jehovah to, "Examine me, O Lord, and prove me; try my reins and my heart" (Ps. 26:2 KJV), he was speaking of his emotions. The Hebrew word translated reins in this verse means "seat of emotion and affection."
David, the man who asked one thing from the Lord—to dwell in His house all the days of his life and to gaze on His beauty and seek Him in His temple (see Ps. 27:4)—was confident in who he was in God. Despite the warfare, despite the betrayal, despite the rejection—despite it all—David submitted his emotions to God.
