EVERY WORD YOU READ IN THE SCRIPTURE NOW IS TALKING TO YOU NOW. All the characters found in it – Peter, Moses, Samuel, Thomas, James, John, Jonas, etc relates to someone NOW in Christendom. Your life NOW might fit into the Abraham or Isaac or Jacob or Moses or Aaron or Mariam or Elijah or Elisha or the Pharisees/Saducees/Scribes or Judas or Paul or Samson or David, etc, character. And a WISE Believer is supposed to learn from the mistakes these characters made so as not to make same, attaining perfection.
2 Timothy 3
16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
17 That the man of God may be perfect, throughly furnished unto all good works.
