Before we conclude this I want to point out the similarity of What Peter said to Israel on Pentecost.
Acts 2:22-3:16 “Men of Israel, hear these words: Jesus of Nazareth, a Man attested by God to you by miracles, wonders, and signs which God did through Him in your midst, as you yourselves also know— “Him, being delivered by the determined purpose and foreknowledge of God, you have taken by lawless hands, have crucified, and put to death; “whom God raised up, having loosed the pains of death, because it was not possible that He should be held by it. “For David says concerning Him: ‘I foresaw the Lord always before my face, for He is at my right hand, that I may not be shaken. Therefore my heart rejoiced, and my tongue was glad; moreover my flesh also will rest in hope. For You will not leave my soul in Hades, nor will You allow Your Holy One to see corruption. You have made known to me the ways of life; you will make me full of joy in Your presence.’ “Men and brethren, let me speak freely to you of the patriarch David, that he is both dead and buried, and his tomb is with us to this day. “Therefore, being a prophet, and knowing that God had sworn with an oath to him that of the fruit of his body, according to the flesh, He would raise up the Christ to sit on his throne, “he, foreseeing this, spoke concerning the resurrection of the Christ, that His soul was not left in Hades, nor did His flesh see corruption. “This Jesus God has raised up, of which we are all witnesses. “Therefore being exalted to the right hand of God, and having received from the Father the promise of the Holy Spirit, He poured out this which you now see and hear. “For David did not ascend into the heavens, but he says himself: ‘The Lord said to my Lord, “Sit at My right hand, Till I make Your enemies Your footstool.” ‘ “Therefore let all the house of Israel know assuredly that God has made this Jesus, whom you crucified, both Lord and Christ.” Now when they heard this, they were cut to the heart, and said to Peter and the rest of the apostles, “Men and brethren, what shall we do?” Then Peter said to them, “Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit. “For the promise is to you and to your children, and to all who are afar off, as many as the Lord our God will call.” And with many other words he testified and exhorted them, saying, “Be saved from this perverse generation.” Then those who gladly received his word were baptized; and that day about three thousand souls were added to them. And they continued steadfastly in the apostles’ doctrine and fellowship, in the breaking of bread, and in prayers.
Both refer to David and both refer to Jesus crucifixion for their sins will be forgiven.
The reaction to Paul and Barnabas- Acts 13:42-43 “So when the Jews went out of the synagogue, the Gentiles begged that these words might be preached to them the next Sabbath. Now when the congregation had broken up, many of the Jews and devout proselytes followed Paul and Barnabas, who, speaking to them, persuaded them to continue in the grace of God.”
Notice that Barnabas was with Paul when he spoke this gospel invitation. Barnabas as one of the apos accompanied Paul with his calling to the Gentiles. Acts 13:43-47: “Now when the congregation had broken up, many of the Jews and devout proselytes followed Paul and Barnabas, who, speaking to them, persuaded them to continue in the grace of God. On the next Sabbath almost the whole city came together to hear the word of God. But when the Jews saw the multitudes, they were filled with envy; and contradicting and blaspheming, they opposed the things spoken by Paul. Then Paul and Barnabas grew bold and said, “It was necessary that the word of God should be spoken to you first; but since you reject it, and judge yourselves unworthy of everlasting life, behold, we turn to the Gentiles. “For so the Lord has commanded us: ‘I have set you as a light to the Gentiles, that you should be for salvation to the ends of the earth.’
Paul concentrated on the cross and the person of Christ in salvation. Maybe the people today are angry at Paul’s epistle to the Galatians when he spoke of the law keepers who came into the church to bring them into bondage. Gal. 2:4-5 “… false brethren secretly brought in (who came in by stealth to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage), to whom we did not yield submission even for an hour, that the truth of the gospel might continue with you. Gal. 3:10-11 “For as many as are of the works of the law are under the curse; for it is written, “Cursed is everyone who does not continue in all things which are written in the book of the law, to do them.” But that no one is justified by the law in the sight of God is evident, for “the just shall live by faith.” These men were adding the Messiah to their law not understanding the new covenant made by Him.
