"Born again" wasn't a term invented by the popular press or religious fundamentalists. It was something Jesus told Nicodemus must happen for anyone to enter heaven (see John 3:3). Peter certainly heard that term from Jesus and speaks of it here (as well as in 1 Peter 1:23). It's a term synonymous with being saved and having eternal life. What does this new birth provide? In a word—solidity! Coming to Christ brings hope, inheritance, and power.
