 | With many other words he warned them; and he pleaded with them, "Save yourselves from this corrupt generation." Those who accepted his message were baptized, and about three thousand were added to their number that day. |
 | And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation. Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls. |
The apostle Peter was preaching the first sermon to a newly formed church. Just before this, he is calling people to repentance. But being saved from 'this corrupt generation' implies that the people were not just individual sinners, but a product of the mindset of a generation. Therefore, their thoughts were not to be focused any more upon the prevailing mindsets, but upon by the spirit and truth of God. Becoming a Christian changes the way we look at everything; including ourselves. The gospel forms a new generation within the corrupt generation in which we live.
