"For Demas hath forsaken me, having loved this present world, and is departed unto Thessalonica .... Only Luke is with me. Take Mark, and bring him with thee: for he is profitable to me for the ministry .... Alexander the coppersmith did me much evil: the Lord reward him according to his works." 2 Timothy 4:10,11,14

Luke - began well and ended well
Demas - began well and ended badly
Mark - began badly and ended well
Alexander - began badly and ended badly
