CHAPTER VII. _THE FIRSTFRUITS OF PENTECOST._ "Now when they heard this, they were pricked in their heart, and said unto Peter and the rest of the apostles, Brethren, what shall we do? And Peter said unto them, Repent ye, and be baptized every one of you in the name of Jesus Christ unto the remission of your sins; and ye shall receive the gift of the Holy Ghost. For to you is the promise, and to your children, and to all that are afar off, even as many as the Lord our God shall call unto Him."--ACTS ii. 37-39. The sermon of St. Peter on the day of Pentecost and the sermon of our Lord present a striking contrast. Our Lord's sermons were of various kinds; they were at times consoling, yet full of instruction and direction. Such, for instance, was the Sermon on the Mount. At other times His discourses were stern, and full of sharp reproof. Such was His teaching in His parting addresses to the Jews delivered in the temple, recorded in the synoptic Gospels. Yet they apparently failed, for the time at least, in producing any great practical results. In fact, His temple discourses served only to irritate His foes, and arouse their hostility. St. Peter delivered a sermon on the day of Pentecost which was quite as stern and quite as calculated to irritate, and yet that discourse was crowned with results exceeding those ever achieved by our Lord, though His discourses far surpassed St. Peter's in literary skill, in spiritual meaning, in eternal significance and value. Whence came this fact? It simply happened in fulfilment of Christ's own prophecy recorded by St. John, where He predicts that His Apostles shall achieve greater works than He had achieved, "because I go unto the Father" (John xiv. 12). The departure of Christ into the true Holy of Holies opened the channel of communication between the eternal Father and the waiting Church; the Spirit was poured out through Christ as the channel, and the result was conviction and conversion; leading the people to cry out, in response to St. Peter's simple statement of facts, "Men and brethren, what shall we do?"
