Acts 3 · a question people ask

Peter says, "I know that you did this in ignorance" (3:17). If they didn't know, why does he call them to repent?

In the text

Peter says both, one after the other, and these notes don't fit them together for him. "Now, brothers, I know that you did this in ignorance, as did also your rulers. But the things which God announced by the mouth of all his prophets, that Christ should suffer, he thus fulfilled." (3:17-18). Then, "Repent therefore, and turn again, that your sins may be blotted out" (3:19). The chapter gives no more of his words on how the two go together. He is speaking to those in front of him (3:12), and these notes apply his words to no one today.

The verses

“When Peter saw it, he responded to the people, “You men of Israel, why do you marvel at this man? Why do you fasten your eyes on us, as though by our own power or godliness we had made him walk?”
Acts 3:12 · World English Bible
““Now, brothers, I know that you did this in ignorance, as did also your rulers. But the things which God announced by the mouth of all his prophets, that Christ should suffer, he thus fulfilled. “Repent therefore, and turn again, that your sins may be blotted out, so that there may come times of refreshing from the presence of the Lord,”

From Favor's study of Acts 3

Acts 3: What I have, that I give you

Peter fastened his eyes on the lame man (3:4), then asked the people why they fastened their eyes on him and John (3:12): in Acts's Greek, one verb. And the man's feet "received strength" (3:7) by the same verb Peter uses when he says Jesus's name "has made this man strong" (3:16).

In Favor, questions like this come up right where they arise as you read, with the Hebrew and Greek behind the words and how the chapter leads to Jesus.
