29 And when they had carried out all that was written of him, they took him down from the tree and laid him in a tomb. 30 But God raised him from the dead, 31 and for many days he appeared to those who had come up with him from Galilee to Jerusalem, who are now his witnesses to the people. 32 And we bring you the good news that what God promised to the fathers, 33 this he has fulfilled to us their children by raising Jesus, as also it is written in the second Psalm, “‘You are my Son, today I have begotten you.’ 34 And as for the fact that he raised him from the dead, no more to return to corruption, he has spoken in this way, “‘I will give you the holy and sure blessings of David.’ 35 Therefore he says also in another psalm, “‘You will not let your Holy One see corruption.’ 36 For David, after he had served the purpose of God in his own generation, fell asleep and was laid with his fathers and saw corruption, 37 but he whom God raised up did not see corruption. 38 Let it be known to you therefore, brothers, that through this man forgiveness of sins is proclaimed to you, 39 and by him everyone who believes is freed from everything from which you could not be freed by the law of Moses. 40 Beware, therefore, lest what is said in the Prophets should come about:
41 “‘Look, you scoffers, be astounded and perish; for I am doing a work in your days, a work that you will not believe, even if one tells it to you.’”
Now Paul moves to the "good news". What would be the point of telling someone about Jesus if you didn't tell them what Jesus can do right now? Paul tells his listeners that their forefathers promised it and that Jesus is the fulfillment of it.
The quote from Psalms 2 emphasizes Paul's point. Most people think of this passage like a King declaring to His Kingdom that He is raising up a son to rule someday. But that this day, he and the son would share the throne of the Kingdom together. The fact that God raises Jesus from the dead is is evidence to this fact. Jesus is the fulfillment of the promise made to King David that from his lineage a Savior would come. Paul explains this more fully in Romans 1: 3 - 4 3 concerning his Son, who was descended from David according to the flesh 4 and was declared to be the Son of God in power according to the Spirit of holiness by his resurrection from the dead, Jesus Christ our Lord,
Next Paul quotes Isa 53:3 “‘I will give you the holy and sure blessings of David.’ This blessing could not be fulfilled without the resurrection of Jesus.
He quotes Psalms 16:10 “‘You will not let your Holy One see corruption.’ David was dead, his body has been corrupted. Jesus isn't dead, His body is not corrupted.
Paul finishes by stating that through Jesus, one could be forgiven of their sins. That one could even be free from the guilt of those things which the Law of Moses could not address.
Paul concludes by quoting Habakkuk 1:5 “‘Look, you scoffers, be astounded and perish; for I am doing a work in your days, a work that you will not believe, even if one tells it to you.’” It's a warning from Paul that they should watch out for a greater judgement if they don't listen to him.
Ministering to the religious lot is difficult at best. Paul was a master at it, simply because he use to be one. It is always easier to help someone discover their faith than to change their faith. But what you and I face today is even harder. People place their faith in things, education, their careers and so much more. Getting them to change their faith to Jesus requires the skill of a Paul. But that is what the Holy Spirit is for. To help us do what we cannot do for ourselves. Trust in Him and let Him change your life.
