1. Repent (17-20)
How can there be hope for sinners who killed the Author of life? There is hope, for as he promised, God sent Christ to suffer for the sake of sinners. He did not send a mighty warrior to save his people; he sent a suffering servant. If any sinner repents and accepts Christ, God will wipe out his sins and give him a refreshing new life. The Spirit of Christ indwells forgiven sinners; Jesus will come in glory at the end of the age to restore all things.
2. God's promises are sure (21-26)
God spoke through his holy prophets about the Christ. Moses said that God would raise up a prophet who would speak with the absolute authority of God. All of the prophets spoke about the coming Christ. But at the root of all the prophecies is God's covenant with Abraham: 'Through your offspring all peoples on earth will be blessed.' Forgiveness of sin is the best blessing.
Application: Lord, thank you for making me an heir of your best blessing.
One Word: Repentance & times of refreshing
