1. The historical facts of this day, as well as the beautiful sermon the Holy Spirit delivered through the apostle Peter, which might appropriately be fully treated at this time, we shall leave for the special sermons on the various festivals of the year. For the present we will but briefly speak of the occasion of this festival, and of the office of the Holy Spirit.
2. The festival we call "Pentecost" had origin as follows: When God was about to lead the children of Israel out of Egypt, he permitted them to celebrate the Feast of the Passover on the night of their departure; and commanded them on every annual recurrence of the season to observe the same feast in commemoration of their liberation from bondage and their departure from Egypt. Fifty days later, in their journey through the wilderness, they arrived at Mount Sinai. There God gave them the Law, through Moses; and there they were commanded to observe annually, in commemoration of that giving of the Law, the fiftieth day after the Feast of the Passover. Hence the name "Feast of Pentecost," the word "Pentecost" coming from the Greek "Pentecoste," or "fiftieth day." Our Saxons, rather more in conformity to the Greek, use the word "Pfingsten." So we have it here of Luke: "When the day of Pentecost was now come," or "fully come"—when the Jews had properly commemorated the giving of the Law of God on Mount Sinai—the Holy Spirit came, in accordance with Christ's promise, and gave them a new law. We now celebrate this feast, not because of the old historical event, but because of the new one—the sending of the Holy Spirit. It is in order, then, to give a little instruction concerning the difference between our Pentecost and that of the Jews.
LITERAL LAW AND SPIRITUAL LAW.
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.
THE OFFICE OF THE HOLY SPIRIT.
6. From this we should learn what is the office of the Holy Spirit in the Church, and how or by what means he is received in the heart and works there. In time past it was preached that he merely endorses what the councils conclude and the Pope establishes in the Spiritless papal Church. The fact is, however, the doings of Pope and councils are mere outward matters; they relate to external commands and government. The above theory is, therefore, wholly inconsistent and perverse. Of the work of the Holy Spirit, the Papists make a dead, written law, when it is really a living, spiritual law. Thus they render the Holy Spirit a Moses, and his words mere human prattle. It is all due to ignorance of the character of the Holy Spirit, of the purpose of his coming and the nature of his office. Therefore, let us learn and firmly grasp those things and be able rightly to distinguish the Spirit's office.
7. Observe here, the Holy Spirit descends and fills the hearts of the disciples sitting in fear and sorrow. He renders their tongues fiery and cloven, and inflames them with love unto boldness in preaching Christ—unto free and fearless utterance. Plainly, then, it is not the office of the Spirit to write books or to institute laws. He writes in the hearts of men, creating a new heart, so that man may rejoice before God, filled with love for him and ready, in consequence, to serve his fellows gladly.
