Wearing a cross never converted anyone to biblical Christianity. A person becomes a Christian by accepting Jesus Christ as Lord.
if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. Romans ch 10 v9-10
