Read Acts 3:12-19
12When Peter saw the people, he said to them, “Fellow-Israelites, why are you surprised at this, and why do you stare at us? Do you think that it was by means of our own power or godliness that we made this man walk? 13The God of Abraham, Isaac, and Jacob, the God of our ancestors, has given divine glory to his Servant Jesus. But you handed him over to the authorities, and you rejected him in Pilate’s presence, even after Pilate had decided to set him free. 14He was holy and good, but you rejected him, and instead you asked Pilate to do you the favour of turning loose a murderer. 15You killed the one who leads to life, but God raised him from death—and we are witnesses to this. 16It was the power of his name that gave strength to this lame man. What you see and know was done by faith in his name; it was faith in Jesus that has made him well, as you can all see.
17 “And now, my fellow-Israelites, I know that what you and your leaders did to Jesus was due to your ignorance. 18God announced long ago through all the prophets that his Messiah had to suffer; and he made it come true in this way. 19Repent, then, and turn to God, so that he will forgive your sins. If you do, 20times of spiritual strength will come from the Lord, and he will send Jesus, who is the Messiah he has already chosen for you.
Peter told a lame man to stand up and walk in the name of Jesus - and the man walked. The people were amazed at what had happened and Peter immediately pointed to faith in Jesus.
Its a pity the reading does not include verse 20: "Repent... so your sins may be wiped out, so that times of refreshing may come from the presence of the Lord..."
Pray for 'refreshing' and 'spiritual strength' that comes from God.
