Luke 6:22-23 "Blessed are ye, when men shall hate you, and when they shall separate you [from their company], and shall reproach [you], and cast out your name as evil, for the Son of man's sake. Rejoice ye in that day, and leap for joy: for, behold, your reward [is] great in heaven: for in the like manner did their fathers unto the prophets."
"Luke 6:22-23"
You are mis-interpreting this passage. This refers to rewards in heaven, not forgiveness of sins.
