There are some Christians who teach that logically a person is regenerated before he believes.
However, the following verse demonstrates the 'life" comes as a result of believing:
"Jesus performed many other signs in the presence of his disciples, which are not recorded in this book. But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name" (Jn.20:30-31).
Since "life" comes as a result of believing then it is impossible that regeneration precedes faith.
