What did the Jews in Peter's day have to recognize about Jesus?
The Jews in Peter's day had to recognize that Jesus was the Christ, and only Jesus. There is no salvation in any other, for there is no other name under heaven given among men whereby they must be saved. This verse narrows the way to one Savior.
Les explains that for the Jew at the particular time Peter is dealing with, they had to recognize that Jesus was the Christ, and only Jesus. He emphasizes that there is no other name under heaven given among men whereby we must be saved, and that this verse is narrow, bringing it right down to only one way. Les notes that while many sincere people follow a cult leader, Buddha, Muhammad, or whatever, salvation is only in Christ. He also points out that the vast majority of Jews rejected it, but thousands did embrace Christ early on, as archaeology is proving, though the nation let the ball drop and God went to the Gentile.
