3. The occasion of the Jews' observance was the giving of the literal law; but it is ours to celebrate the giving of the spiritual law. To present the point more clearly, we cite Paul's distinction of the two covenants. 2 Cor 3, 6. And these two covenants respectively relate to two kinds of people.
4. First, there is the written law commanded of God and composed of written words. It is styled "written" or "literal" because it goes no farther and does not enter the heart, nor are there any resulting works other than hypocritical and extorted ones. Consisting only of letters—a written law—it is wholly dead. Its province being to kill, it ruled a dead people. With dead hearts men could not sincerely observe the commandments of God. Were every individual left to do as he pleased, being uninfluenced by fear, not one would be found choosing to be controlled by the Law.
Unquestionably, human nature is conscious of the fact that while it prefers to follow its own inclinations it is impelled to do otherwise; for it reasons: "If I observe not God's commandments, he will punish me, casting me into hell." Thus our nature is conscious of obeying unwillingly and contrary to desire. Because of the punishment men fear, they soon become enemies to God; they feel themselves sinners, unable to stand before God, and consequently not acceptable to him. Indeed, they would rather there were no God. Such enmity to God remains persistently in the heart, however beautifully nature may adorn itself outwardly. We see, therefore, how the Law, so long as it consists merely of written words, can make no one righteous, can enter no heart. Upon this topic we have elsewhere preached and written at length.
5. The other law is spiritual; not written with ink and pen, nor uttered by lips as Moses read from the tables of stone. We learn from the historical record of the event that the Holy Spirit descended from heaven and filled all the assembled multitude, and they appeared with parting, fiery tongues and preached so unlike they were wont to do that all men were filled with amazement. The Spirit came pouring into their hearts, making them different beings, making them creatures who loved and willingly obeyed God. This change was simply the manifestation of the Spirit himself, his work in the heart. He wrote in those hearts his pure and fiery flame restoring them to life and causing them to respond with fiery tongues and efficient hands. They became new creatures, aware of possessing altogether different minds and different tendencies. Then all was life and light; understanding, will and heart burned and delighted in whatever was acceptable to God. Such is the true distinction between the written law of God and the spiritual. Herein we perceive what is the work of the Holy Spirit.
