Were they qualified to preach it? I do not think any Christian will doubt it. If they were not prepared to teach the Gospel of the Son of God, then I would have no hope, my friends, of hearing it in this life. Never. Jesus himself chose them. He ordained them; he instructed them, and after all this, as you will find, in the 2nd chap, of the Acts of the Apostles, 1st, 2nd and 3rd verses, they assembled in Jerusalem, and had fulfilled unto them the promise of the Lord Jesus Christ, receiving the endowment of which I have been speaking. I think that all my friends here are certainly prepared to accept the words that Peter spoke, and acknowledge them to be true. What did Peter say? First, he preached Christ and him crucified. You see the people, who had gathered together on the day of Pentecost, were people who had no faith in Christ. They had rejected him and his instructions. They had been of those who persecuted Christ and the apostles. They were of those who had either personally or in their sympathies sustained the crucifixion of the Lord Jesus. Therefore, Peter, knowing this, stood up and preached to them, first Christ and him crucified, and he was successful. Who can doubt it? Peter, a servant of God, ordained by the Son of God. Peter, upon whom the Spirit of God rested as tongues of fire, as the Scriptures have it. This man stood up and argued the point, and explained about Jesus. And who can doubt the result? I am sure we would have been disappointed {126} if we had been told in the Bible that Peter was not successful. He was successful. Many believed on him, and the result of their belief was that they said, "Men and brethren, what shall we do?" (Acts ii, 37). No wonder they asked that question. People who had either helped to crucify the Lord, or who had rejoiced when he was crucified, as many of them did, to be convinced that that same Jesus whom they had assisted to crucify was indeed the Lord, the Christ, and when they were convinced of this they cried out, "Men and brethren, what shall we do?" Peter was prepared to tell them. He had the very instructions that were needed, and the words of Peter are applicable to-day, my friends, to you and to me, so far as we have not obeyed them. We are believers in Christ, I trust. We have fortunately made our appearance in this life, in the midst of a people who at least believe in the divinity of Christ, and we have received impressions favorable to this end; therefore the words of Peter, spoken to those who believed in the divinity of Christ, are applicable to us, and are the words of salvation to us, if that ancient Gospel is not changed. What were the words? He says, "Repent, and be baptized every one of you in the name of Jesus Christ, for the remission of sins, and ye shall receive the gift of the Holy Ghost." (Acts ii, 38).
