The first Christians were practicing Jews who lived their lives the way Jesus taught them. Christianity was not a religion until after Jesus was elevated to a deity. The deification of Jesus came long after Jesus' death.
So, practicing Jew have never lived their life according to the Bible. Jesus' original followers did not either as the Bible did not exist. The first book of the New Testament to be written was The Book of Acts which was written about 4 decades after the events in the alleged events in the book were to have taken place.
