This is nothing less than the promise of the gospel. What we try to do and cannot do, God promises to do and does do for us. The natural human being "is not subject to the law of God, neither indeed can be" (Rom. 8:7). But God Himself writes His law in the heart. This is conversion and regeneration.
Every true believer is "the epistle of Christ...written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart" (2 Cor. 3:3). The Spirit writes the law of God in the heart "that the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit" (Rom. 8:4). Such consecrated Christians are "in Christ," and Christ dwells in them by faith.
Campbell Morgan tells of visiting in a home in which he always smelled the strong fragrance of roses. One day he asked his host the reason for this. The reply was: "While in the Holy Land 10 years ago, I bought a small tube of attar roses. It was wrapped in cotton wool and, as I was standing here unpacking it, I broke the bottle. I put the broken container, cotton wool, and all, into that vase on the mantel." There stood the beautiful vase, and as the lid was lifted, fragrance filled the room. The perfume had permeated the clay of the vase, and it was impossible for one entering the room not to be conscious of it.
If Christ is given preeminence in the life of a Christian, the fragrance of the Rose of Sharon will pervade, permeate, and bless the entire life, and others will be conscious of the presence of One unseen.
MEDITATION PRAYER: "I have longed for thy salvation, O Lord; and thy law is my delight" (Ps. 119:174).
