When Peter saw this, he said to them: “Fellow Israelites, why does this surprise you? Why do you stare at us as if by our own power or godliness we had made this man walk? 13 The God of Abraham, Isaac and Jacob, the God of our fathers, has glorified his servant Jesus. You handed him over to be killed, and you disowned him before Pilate, though he had decided to let him go. 14 You disowned the Holy and Righteous One and asked that a murderer be released to you. 15 You killed the author of life, but God raised him from the dead. We are witnesses of this. 16 By faith in the name of Jesus, this man whom you see and know was made strong. It is Jesus’ name and the faith that comes through him that has completely healed him, as you can all see.17 “Now, fellow Israelites, I know that you acted in ignorance, as did your leaders. 18 But this is how God fulfilled what he had foretold through all the prophets, saying that his Messiah would suffer. 19 Repent, then, and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord, 20 and that he may send the Messiah, who has been appointed for you—even Jesus. 21 Heaven must receive him until the time comes for God to restore everything, as he promised long ago through his holy prophets. 22 For Moses said, ‘The Lord your God will raise up for you a prophet like me from among your own people; you must listen to everything he tells you. 23 Anyone who does not listen to him will be completely cut off from their people.’24 “Indeed, beginning with Samuel, all the prophets who have spoken have foretold these days. 25 And you are heirs of the prophets and of the covenant God made with your fathers. He said to Abraham, ‘Through your offspring all peoples on earth will be blessed.’ 26 When God raised up his servant, he sent him first to you to bless you by turning each of you from your wicked ways.”
In sharing the gospel, I often feel like you can't share the good news until you've shared the bad news so that they can better appreciate how good the good news is. Does that make sense? Here Peter does exactly that. He basically says, "God sent His servant Jesus, who is God- the author of life, and you handed Him over to be killed. Pilate was going to let Him go but you insisted He be killed even to the point where you chose a murderer over this innocent man. You disowned Him, the One that Moses, Abraham, Samuel, and all the prophets predicted would come and have received the predicted penalty for that which is your transgressions have cut you off, you've lost the blessing of God, and your peace is gone." That's pretty harsh with a lot of finger pointing, right? Our presentations don't usually go like this, do they? We present a winsome gospel and woo people in. We focus on meeting people's needs not addressing their sins.
The illustration I use is a person goes to the doctor because he is tired all the time. The doctor says, "You just need vitamins. Take these and you'll feel better." After a while he doesn't so he goes to the next doctor who sends him to a dietitian to eat healthier. This doesn't work so he goes to the next and is put on iron, and the next who gives him probiotics, and the next who starts him on an exercise program, and the next who gives him anti-depressants and so on. Nothing works. He finally finds a doctor who tells him he has a cancerous tumor sapping his energy and unless it's cut out, he will die. Now, he has a choice - believe all the others who said that he's basically Ok he just needs to get better, or believe the doctor who says that he's not OK, he's dying and needs drastic measures. The last doctor is Christianity. The Bible gives us a bad diagnosis while every other religion says, "You're basically good, do this and you'll be OK." The Bible says, "You're dead in your sins, separated from God, headed to eternal death unless you surrender to the radical cleansing on the inside by the blood of Christ. This is the only hope." The patient must then make a choice - do I believe that doctor? Does his remedy resonate with reality or do I believe the majority?
Peter starts with the bad diagnosis, they have sinned and are separated from God. He then gives them the remedy - repent and believe in Jesus. He then gives them the prognosis - if they do that, they will be forgiven, their relationship with God and the blessings from that will be restored, their soul will be refreshed and someday Jesus will come back to them.
We are not good people who just have some flaws to address to increase our goodness so we can go to heaven when we die. We have rejected God and chosen to be our own gods and are reaping the bad results of this and will for all eternity. Let's turn from our evil ways and surrender to the One who loves us so much that He willingly suffered for us and died on the cross so we can live forever with Him. That resonates with me!
