A Big Mistake – April 20, 2026
Read: Acts 2:14,32-41
Then Peter stood up with the Eleven, raised his voice and addressed the crowd: “Fellow Jews and all of you who live in Jerusalem, let me explain this to you; listen carefully to what I say. God has raised this Jesus to life, and we are all witnesses of it. “Therefore let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Messiah.” When the people heard this, they were cut to the heart and said to Peter and the other apostles, “Brothers, what shall we do?” Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit. The promise is for you and your children and for all who are far off—for all whom the Lord our God will call.” Acts 2:14,32-41 (selected verses)
A Big Mistake
In the name of the Father and of the Son and of the Holy Spirit. Amen.
Lucas was riding in the car with his dad when the car started to shake violently. Warning lights came on all over the dashboard. He looked at the flashing lights and felt worried. His dad quickly pulled over, reached into the glove compartment to check the car’s instruction book. Lucas heard his dad mutter something about how the car’s computer and the engine stopped talking to each other and that he could not drive it anywhere. Now Lucas was scared: “Are we stuck? How will we get home? What would they do without their car?”
Lucas watched as his dad called his uncle who lived nearby to come and take a look. It felt like forever, but finally his uncle arrived and opened the hood. As soon as his uncle looked under the hood, he laughed. It was an easy and simple fix—a hose had loosened and become detached. With one small click, the car was as good as new. “Whew!” Lucas sighed with relief. What seemed like a huge problem turned out to be something small.
The people in our reading today felt awful when Peter confronted them with what they had done. They had crucified the Son of God. They realized they had made a very big mistake. But Peter wasn’t finished—he continued to tell them that God had made “the Jesus, whom [they] crucified, both Lord and Messiah.” God had taken the horrible thing they had done and made it into something wonderful.
Peter tells them of a promise that comes to them because of Jesus’ death. They will receive the forgiveness of sins through Jesus Christ. Instead of only guilt, they received forgiveness. The best part of this reading for us, might be when we hear Peter say that this promise isn’t just for the people he is talking to. It’s for us too! It is for all believers of all time.
Jesus’ crucifixion was a horrible and sinful event that God used for the good of his people. We have a true hope of forgiveness because of it. Because he lives, I know that I will live too in heaven with him one day. God turned the worst thing into the best news.
Prayer:
Heavenly Father, you used the death of your Son to give me life and forgiveness. I have a sure hope that I am a child of God and that I will be with you one day. Help me remember that you can bring good even from bad things. In Jesus’ name. Amen.
